I would guess OpenAI uses LaTeX as their default choice because they want to write equations.

I’ve been using Word Equations and never have I needed to use Latex. I think most people are still under the wrong impression that only Latex can handle math expressions. I use my custom shortcuts in Word to speed it up tho.

Using LaTeX does not necessarily imply rendering to PDF.
