FWIW, I've been finding that ChatGPT doesn't use emoji at all when I engage with it like a pair programmer and bounce off design ideas, ask for implementation code, propose refactorings etc. But when I ask it to do data analysis or modeling, the emoji are all over the place, yes. (And judging by what I've seen on GitHub over the last year or so, I would never in a million years consider asking an LLM to write a project README or documentation unsupervised.)
