I'd consider this too nit-picky in most contexts, but we're in a thread about connection-blocking software. PiHole is a DNS server. It cannot block IPs or connections.
I'm with you that Little Snitch style filtering gets annoying, but DOH is going to obsolete PiHole / DNS filtering very fast. Can't filter DOH at the gateway without taking on all the other hassles of MITM and can't prevent an app from using whatever DOH server it chooses.
