To obtain an equivalent of ${}^AB$ in LyX, you can
start an empty math mode box,
type ^ to enter superscript and enter the A,
press space to exit the superscript,
enter the B immediately after the superscript.
Checking View > Source Pane, the above produces $^{A}B$, which compiles as ${}^AB$.
If it is something you need to insert many times, then ...

First, some general comments and observations about the code shown in your preamble:
When using LuaLaTeX or XeLaTeX, you should not load the fontenc and inputenc packages. (Even when using pdfLaTeX, it's no longer necessary to load the inputenc package unless your file's input encoding is not UTF8 or ASCII, which is a proper subset of UTF8.)

The bm package is for legacy 8-bit fonts. In unicode-math, load a math font that comes in bold (currently, XITS Math, Libertinus Math or Minion Math) and use \boldsymbol for bold operators and signs. If you only need bold letters, you can use \mathbf, \mathbfcal, etc. Or the new commands \symbfup for bold upright, \symbfit for bold italic, etc., as Mico ...

As @DavidCarlisle has already noted in a comment, you may want to replace \parallel with \Vert. Importantly, the symbol produced by \Vert can be enlarged vertically with the help of the \big, \Big, \bigg, and \Bigg prefixes: \big\Vert, \Big\Vert, \bigg\Vert, and \Bigg\Vert. Finally, in case you need a bit of extra spacing around the double vertical lines, ...

There are cases where a very high or deep object is better smashed; for instance, in an alignment where a formula ends with a summation and the next is much shorter, we can save vertical space by using \smash[b]{...} around the summation. Also your case can take advantage of smashing because of the short lines of text around the display.
However, one has to ...

You asked,
How can I smash the \sum without changing the horizontal spacing around it?
To \smash the expression without affecting the spacing between \frac{1}{N} and \sum, insert an empty math atom -- {} -- as the first element of the argument of \smash. For instance,
\bar{x} = \frac{1}{N}\smash{{}\sum_{n=1}^N x_i}

I was able to recreate the issue you've experienced on the Wikipedia site by using \dfrac instead of \frac.

The second method employs \tfrac instead of \frac (or \dfrac). Given that ...

I cannot reproduce the output you get with your code.

Despite the many reasons not to do it this way, and Alan's comment provides a link about not using \ensuremath, I nonetheless suggested placing an \ensuremath around the code, as in
\newcommand*{\pdiffat}[3]{\ensuremath{\left(\frac{\partial{#1}}{\partial{#2}}\right)_{#3}}}
In this manner, the command will function when invoked in either text or math modes.

Remove the spaces between the \newcommand* and the command name, they seem to confuse the overleaf parser. This here works fine for me:
\newcommand*{\pdiffat}[3]{\left(\frac{\partial{#1}}{\partial{#2}}\right)_{#3}}

You are redefining \familydefault to be equal to \sfdefault. This means that polyglossia is looking for a sans serif cyrillicfont. You can set it up with
\newfontfamily\cyrillicfontsf{Arial}[Script=Cyrillic]
It would be probably also a good idea to setup \cyrillicfonttt for the typewriter font.

Just for reference, here's a solution which does not employ the optidef package. Instead, it employs 1 align* environment (for the 4 "outer" blocks) and 1 aligned environment (for the group of 3 "inner" blocks which, together, make up the final "outer" block). align* and aligned are both provided by the amsmath package.

I'll be happy to remove this post. According to what I find, you just need to move the position of the = sign in

\addConstraint{\dot{\mathbf{x}}}{ =\mathbf{f}\left(\mathbf{x},\mathbf{u},t\right)}

Equations in roff
roff (or groff or any other implementation) doesn't actually support mathematics typesetting. To this end you have to use a preprocessor which transforms equations in your document into something that groff can read. I'm only aware of the eqn preprocessor for equations but there might be others.
One obvious downside of eqn (or groff in ...

\textbackslash is a text-mode command, so it does not work in math-mode (as you may have noticed) because math fonts are wildly different from text fonts, so the characters are set up differently, so they are not at all compatible. in math-mode you'd use \backslash if you wanted the backslash math symbol.
