You can search https://matrixrooms.info, though remember to do your research on the homeserver in the room address before joining, as the list is quite unfiltered; there does seem to be some art rooms but only one functional TTRPG room (the glasgow.social one). Aside from that rollenspiel.chat is a German TTRPG homeserver, though I don't know how active that is.
