LLMs talk like people; there is nothing wrong with this. It's perfectly fine to be nice to something even if it isn't human. It's why we don't go around kicking dogs for fun.
I understand why people don't act polite to LLMs, but honestly I think not thanking them will make people act more dickish to other humans.
