Probably because LLMs hallucinate and often answer with the wrong information. Can you imagine Siri spitting out wrong information, causing some accident or health risk? Apple's pristine PR image would never allow something like that. Quite frankly, I'm surprised that Google and Microsoft are willing to take that risk.
I totally get why OpenAI said "f it, let's just ignore hallucination and accuracy" that only affects 5% of queries. OpenAI does not have an established worldwide brand.
But could you imagine the news stories if Apple released ChatGPT?
