That's is probably one good usage of LLMs. LaTeX was a relief to deal with after using LLM. I have been using LaTeX for years before but it was not any easy. Aside of making LLM write the text, it is very good grammar and typo checker.

Even on overleaf and browser default spell checker, my Thesis feedback contained a few typos from my Advisor each time I sent him for review.

BTW: Overleaf added LLM integration which help solving LaTeX errors but you pay for it separately. But I feel like overleaf with their good docs on LaTeX something positive for science and hope they manage to adapt with this nee competition.
