Apple's assumption seems to be that the only reason you'd want to turn the LLM features off as a consumer is that you're a parent and you don't want your children interacting with LLMs. So they put it where "parent trying to lock down their child's computer" settings are.

(If you look, most other toggles that appear under "Content & Privacy Restrictions" are for similar things: things Apple provides no more-visible setting to disable; because they think you have "no reason" to turn these features off; because these features are, at least in Apple's opinion, "unobtrusive" [i.e. only really doing something if explicitly activated] and "costless.")

In contrast, I presume the underlying setting identifier, as appears in `defaults` and/or MDM profiles, has a more sensible hierarchical prefix based on what potential risks an organization would see in a roll-out of LLM use.

ETA: yes: the macOS settings domain for "LLM stuff" is `com.apple.applicationaccess`, and the declarative-configuration namespace is `com.apple.configuration.intelligence.settings`. Neither of which has anything to do with parental controls per se (though `com.apple.applicationaccess` is generally where MDM settings related to preventing employees from using "potentially insecure" device capabilities live.)

There's also the declarative-configuration namespace of `com.apple.configuration.external-intelligence.settings` ...which is a bit of a bass-ackwards use of their own declarative configuration model, since if it had been `com.apple.configuration.intelligence.external.settings` instead, then the settings in the enclosing "intelligence" namespace would serve as fallback defaults for the external-intelligence specific settings. Ah well.
