The idea isn't that you tell it to simply change what it wrote on the first try. The idea is that having a first draft to work with allows it to rewrite a better version.
What if someone refers to x part of their body incorrectly? What if they're not able to think clearly due to y reasons and tell it something completely wrong?
An LLM is wholly inappropriate.
As for its "bedside manner"/how polite or friendly it is, that's meaningless if it isn't good at what it does. Some of the best docs/profs I've known have been very detached and seemingly unfriendly, but I'll be damned if they weren't great at what they do. Give me the stern and grumpy doc that knows what they're doing over the cocksure LLM that can't reason.
