I've dealt with this particular bot problem as a mod. Noticing the pattern early on was easy because they always had posts on TEMU subreddits. Now that those subs are banned, it's harder.
Comment length. Their comments are always less than two lines long.
Tone. They always contain at least one exclamation point, and tend to have a tone that I'd say is "cheery to the point it's offputting."
Context. Reading them, a lot of the time you'll ask "did they even read what they're replying to?" The comment seems related, but directly misses the main point.
History. Look at the rest of their comments. If more than one ends in two emojis, they're definitely part of this particular bot network.
How can you tell that’s it an AI generated comment?

what is a TEMU subreddit?
A subreddit about TEMU.
Is there a way to prevent them from flooding the fediverse, or will that fall onto the shoulders of mods to find and delete them?
They can defederate from hexbear. But that's up to each instance individually.
