There’s a way to redirect any port 53 traffic back to your pihole if you have enough control over the gateway, but I don’t know if it’s worth doing. Breaks a bunch of things you’d normally do to debug whatever.
Been doing this a few years, after seeing lots of apps and devices using 8.8.8.8 despite being given my resolver back via DHCP (so obviously hard-coded into them and they’re ignoring os dns.)
No practical drawbacks so far, although I have found many “open resolvers” online from my home, only to realize it’s the redirection messing things up.
