lakeTetra The Pixel will serve as a router/hotspot. Sharing the phone's VPN with a desktop pc over a hotspot seems to require root. Is there a way to share the VPN over a hotspot without?

lakeTetra Adaway needs root to block ads on a system and app level.
You can block ads system-wide using an app such as RethinkDNS, which will use the VPN slot. Last I tried it it had lots of customisation options, lots of filter lists, etc. You can use it as an ad blocker along with connecting to a VPN tunnel with a Wireguard config file.
No idea about no. 2.
