First rule is - if you don't write it, don't expect me to read it. If you AI-write something, then let me get an AI to read it too.

The only solution I can think of is to get AI implemented upstream in the planning phases so that it results in specs for spec-driven development. Your boss will be able to directly contribute without bothering anyone, but he will also think developers are obsolete. You need to warn him about the dangers of vibe-coded shit, but either way there's no positive scenario these days.

you should take the information the same way whether it was produced by him manually or with the help of AI. If you won't someone else who needs a job more will.

Have you talked to him about it?

And what do your colleagues feel?

Just ignore it and they'll get bored and move on to the next thing

I feed it back to AI to respond with em-dashes, en-dashes and clearly Claude-like writing.
