There appears to be support for font-lock for LaTeX expressions in org
but the regex that is used to determine LaTeX snippets is nil:

    org-latex-and-related-regexp is a variable defined in ‘org.el’.
    Its value is nil

    Documentation:
    Regular expression for highlighting LaTeX, entities and sub/superscript.

Maybe play around with this?
