From what I've seen, people generally do not like reading a generated content, but every time I've seen the author come back and say "I used it because it isn't my main language" the community always takes back the criticism. So I'd just be upfront about it and get ahead of it.
Even if you don't agree with it, publishing AI generated content will exclude from ones audience the people who won't read AI generated content. It is a tradeoff one has to decide whether or not to make.
I'm sympathetic to someone who has to decide whether to publish in 'broken english' or to run it through the latest in grammar software. For my time, I far prefer the former (and have been consuming "broken english" for a long while, it's one of the beautiful things about the internet!)
It's clear that this isn't what OP was doing. The LLM was writing, not merely translating. dang put it well:
