LLMs definitely can do this. The output tends to be overly positive though, claiming that any sort of rough draft you give them is "great, almost ready for publishing!". But the feedback you can get on clarity, narrative flow, weak spots... _is_ usually pretty good.
Now, following that feedback to the letter is going to end up with a diluted message and boring voice, so it's up to you to do with the feedback whatever you think best.
