Yeah, I think it's coded to be super-conciliatory as some sort of apology for its hallucinations, but I find it annoying as well. Part of it is just like all automated prompts that try to be too human. When you know it's not human, it's almost patronizing and just annoying.

But, it's actually worse, because it's generally apologizing for something completely wrong that it told you just moments before with extreme confidence.
