There is no function that does just what you want; you need to make them
do what you want. E.g.
(save-excursion
(condition-case nil
(progn (forward-sexp 1) t)
(scan-error nil)))
Note that "test if a parenthesis in LaTeX (latex-mode) starts a balanced
expression" is a kind of weird request, because it will only return nil
if there's a missing close-paren but not if there are too many
close-parens, i.e. it only detects one half of the imbalances.
