"bbhostshow" lists the full bb-hosts file, with all of the includes
done. Or you can query the hobbitd daemon with
   bb 127.0.0.1 "hobbitdboard test=info fields=hostname"
to get a list of the currently known hosts.

Matching that against the directory names in ~hobbit/data/rrd/ would be
fairly trivial, and then you can use the 
   bb 127.0.0.1 "drop HOSTNAME"
to completely cleanup those hosts that no longer exist.
