I've seen this expressed as a concern even from one of my colleagues. My retort was:

"English is not my native language and LLMs taught me quite a few very useful formalisms that do land well for people and they change their attitude towards you to be more respectful afterwards. It also showed me how to frame and reframe certain arguments. I agree sounding like an LLM is kind of sad but I am getting a lot of educational value -- and with time I'll sneak my own voice back in these newly learned idioms and ways to talk."
