I would like to denote the interior of a set using the three letters "int". However, $\int$ clearly doesn't work as that is the integral sign. I would like it to look similar to how "min" looks when typing $\min$ in latex.

This should do it.




    \interior A&\\
    \exp A&\\

The package https://ctan.org/pkg/amsopn is part of https://ctan.org/pkg/amsmath. The manual at https://ctan.org/pkg/short-math-guide might be useful for you, for example section 3.15. It is also found on page 48 of https://ctan.org/pkg/lshort-english. A discussion on manuals is found in What are good learning resources for a LaTeX beginner?.
