From your debug log:

-rw-r--r-- 1 root root 365 Dec 30 11:59 /etc/pihole/blacklist.txt
   112.85.42.237
   ...
   b37yog4wo22elk24i6i566zx4mbqeaqbaeaq.a.e.e5.sk

The domain in question is on your blacklist, and it was blocked by Pi-Hole when the query was A or AAAA. Pi-Hole does not filter other types of DNS queries (TXT, ANY, SOA), so that behavior is expected.

Side note - having an IP in the blacklist has no effect. If a client has an IP, it won't request resolution of that IP.

Pi-Hole does not filter other types of DNS queries (TXT, ANY, SOA), so that behavior is expected.

Note that the upcoming version 5.0 of Pi-hole extends blocking to all kinds of requests (some types may get useless data returned if blocked).
