btree_gist knows nothing of citext, so it's not providing any suitable operator class.
(Code-wise it probably wouldn't be that hard to add, but I see no good way to deal with the inter-extension connection other than to give btree_gist a hard dependency on citext, which people wouldn't appreciate too much.)
I'd expect that creating a "btree_gist_citext" extension would provide a pathway forward here. IIUC, it could even depend on the two extensions it is expanding upon.
