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".

Also, "Es hat in die Ecke gepinkelt". Which pronoun you use is just as dependent on the context as in english.

I have not met a single German that has ever uttered this sentence. (Relating to a dog, that is)

Neither have I, but mostly because either the person knows the gender of the animal or the situation just never came up. The closest that I would say is "Es scheißt gerne aufs Auto" when talking about pidgens (die Taube), but even then you generally talk about multiple, resulting in "Sie scheißen gerne aufs Auto"

Really ? "Es kackt auf's Auto" ? I guess, it might make sense when the person speaking has no specific bird on mind, but only thinks of "das Tier" (the animal). One could also say "er hat .. geckack (der Vogel)", but usually, people wouldn't say "er/sie/es", but use the fully specified noun ("die Taube ... hat..", "der Vogel ht ...", "ein Tier hat ...")

"Es kackt auf's Auto" feels slightly weird to me, if I didn't know whodunnit, I'd probably say something like "irgendwer hat mir aufs Auto gekackt" ("someone pooped on the car"), although there is a also "irgendwas hat mir aufs Auto gekackt" ("something pooped on the car"). My guess is the majority of German would choose the first sentence and anthropomorphize, but maybe I'm projecting.

It's an interesting question, after all. Thanks for bringing it up, haven't talked about pooping on cars for a while ;)

However, "die AI", "Kuenstliche Intelligenz".
