I recently got wrongly accused of using LLMs to help write an article by a reviewer. He complained that our (my and my co-worker's) use of "to foster" read "like it was created by ChatGPT". (If our paper was fluent/eloquent, that's perhaps because having an M.A. in Eng. lit. helped for that.)
I don't think any particular word alone can be used as an indicator for LLM use, although certain formatting cues are good signals (dashes, smileys, response structure).
We were offended, but kept quiet to get the article accepted, and we changed some instances of some words to appease them (which thankfully worked). But the wrong accusation left a bit of a bad aftertaste...
