Assume any part, and assume none of your business.
That said, Apple generally gives people very fine-grained controls over what software features they want enabled, at least compared to other closed-source software vendors.
My question "what part and why" was intended to open up a discussion about privacy in regards to Apple's AI.

This is scary stuff that should not be happening on anything that is closed-source and unaudited publicly. The pervasiveness of surveillance it enables is astounding.
Should we start auditing wallets next? People's driver licenses are sitting insecure and unencrypted in their pockets! Anyone could grab it!
Security is important, but being alarmist toward thoughtful progress hurts everyone.
