I think not passing off LLM text as your own words is common good manners for a number of reasons—including that you are taking responsibility for words you didn’t write and possibly not even read in depth enough, so it’s going to be on you if someone reads too much into them. But it doesn’t really much need any assumptions on LLMs themselves, their theory of mind, etc. Nearly the same would apply about hiring a human ghostwriter to expand on your rough draft, it’s just that that has never been a problem until now because ghostwriters cost a lot more than a few LLM tokens.
