Oh I agree that it's strange, but is it harmful? I'm not being rhetorical, I'm genuinely unsure.
Tangentially, I noticed recently that I'm always fairly respectful in my LLM prompts and often say "thank you" as part of them. LLMs don't need that, but I've come to realize that I'm saying those thing for me. I don't like being disrespectful and expressing gratitude is important to me. Is expressing gratitude to a LLM strange? Perhaps. Is it harmful though? I don't think so.
But yeah, asking an LLM for their name? That seems like something else.
