I can't recall the exact settings to push via ADB, but the Internet Connectivity Check is "easy" to fix. Create a server that's always up that responds with a 301 (or whatever the check expects), and push the address to the phone. Done.

It's a shame that Google's servers are the default, and I wish it were at least called out by Lineage. That said, I doubt they want to cover hosting costs of such a service (although I'd think they'd be fairly minimal).

This internet connection check actually caused problems for us when we started having users in China on android. Our code was checking for a connection before transmitting data and android thought the device was disconnected due to the great firewall. I think there’s just a hack around it for now that disabled the android connection check for those users.

For anyone trying to implement this, the HTTP status code that Android looks for is 204.
