Is there a way to produce blackboard bold Cyrillic letter?
(I know I can do Greek letters with mathbbol
, but I need $\mathbb{Л}$
.)

Not really pretty, but unless you find an open shape Cyrillic font, I see not much more to do.
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage{amsmath}
\DeclareRobustCommand{\bbel}{%
\mathord{\text{%
\ooalign{%
Л\cr
\hidewidth\kern0.125em I\hidewidth\cr
}%
}%
}}
\begin{document}
$x\bbel y^{\bbel}$
\end{document}
For the particular symbol you mention you could fake it by adding a vertical rule to the symbol either to the left or right of the main vertical stem or (egreg's suggestion) print a capital I close to the symbol or double print the symbol with a small separation
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\begin{document}
Л
$\mbox{Л\kern-0.4em\vrule height 1.55ex depth 0ex width 0.08em}$
$\mbox{Л\kern-0.05em\vrule height 1.58ex depth 0ex width 0.08em}$
$\mbox{Л\kern-.15emI}$
$\mbox{Л\kern-0.9emЛ}$
\end{document}
But really one should go back to metafont and make a proper set of symbols.
