  1. there are no errors in the logs and query logging won't initialize
  2. iptables is fully disabled

but the server will respond with "WARNING: recursion requested but not available" because my client 104.200.17.225 is going to external. But the client 'is in' the trusted ACL. Bind is ignoring my trusted list entirely.

Query logging says it is going to external. Why is it ignoring internal and the trusted list? The client is in the list.

try switching your ACL statements

acl "trusted" {
        173.255.211.166;
        104.200.17.225;  //this is the client in question
        10.8.0.0/24;
        10.8.1.0/24;
        127.0.0.1/32;
        ::1/128;
};

acl "outside" {
        any;
};

Your 104.200.17.225 client was matching the "outside" acl first. Rearranging the order of the acls probably helped, but the more reliable way to do this is to exclude your "trusted" address from "outside":

acl "outside" {
        !173.255.211.166;
        !104.200.17.225;  //this is the client in question
        !10.8.0.0/24;
        !10.8.1.0/24;
        !127.0.0.1/32;
        !::1/128;
        any;
};
