I mean, both in English and in german, that's how you would talk to a dog. "Er hat in die Ecke gepinkelt"/"He peed in the corner" (or "she", if it's a female dog).
I don't know what is jarring talking about the chatbot like that.
It may be creepier if you said "she wrote that program for me" as you now assign a specific gender to the chatbot.
It's how you'd talk about a dog that you know the sex of, but if you didn't know you'd probably use "it". An LLM doesn't have a sex or gender, so I think the natural way to refer to them is "it".
in English, maybe. In German, not really. "Der Bot", "der Robot", "der Computer".
However, "die AI", "Kuenstliche Intelligenz".
Also, "Es hat in die Ecke gepinkelt". Which pronoun you use is just as dependent on the context as in english.
