Very very cool. Thank you, once again! I’m thinking about the things my wife and I do with our phones and conveniences we’d miss… seems like mostly small (IMO) usability tradeoffs for far greater independence and privacy.
Not built into the OS. However if you need to, you can use sandboxed Play Services along with the Google app and Google Lens.
Google and Google Lens would require network.
Due to the last point some people prefer to restrict this to a secondary user profile.
Then there are Open Source alternatives one of which is:

For something in between (still using Google libraries but offline):

These are not personal or project recommendations however, I am providing these as they've been discussed in our [Matrix] Community. I don't personally use any and only you know what you're willing to do with your device yet I hope this has been helpful to start your considerations.

GrapheneOS can be used alongside the majority of all the apps you use without loss of convenience. Sandboxed Play Services allows this and you still retain ALL security benefits.
If it is a privacy thing you can start by creating a non personally identifiable Google account and from scratch reasses what and how you give any app or service information.
You can do this in a secondary user too while keeping the base owner profile 'clean' and make gradual instead of drastic changes over time as you see fit.
