Just considering the general situation, $ is hard for Org because it needs to do
“double duty” as both a currency symbol in text, and math delimiters. This means
that it can’t be consistent with how LaTeX works. However, `\( ... \)' doesn’t and
so Org can be much more consistent with LaTeX here. Besides which `$ ... $' is a
TeX-ism and `\( ... \)' is the /proper/ way of doing inline maths in LaTeX, so
really you should be reaching for those anyway.

I’d just use `\( ... \)' in future, and that way you’ll be fine in LaTeX and Org
🙂. You might be able to use `org-element-map' to robustly convert from $ … $=
to `\( ... \)'.

All the best,
Timothy
