I didn't respond before, as I really can't say for sure. No, TV-MA is not an available rating to block. While it is possible to limit a user account to a specific MPAA rating or "safer", I have no idea how it treats unrated material. When I look at the ratings of my media, I see the vast majority of content has no known rating. For the most part, they are titles that were released before the MPAA started rating movies. But I do see quite a number that I know are new enough they should have a rating, such as "The Great Escape".
However, looking up the rating for that movie, I see a major issue with attempting to use them. For this movie, there are dozens of ratings, even within the same country. In the US, there's a different rating for TV vs. playing at a movie theater. And the US movie rating is "Approved", which I had never seen before, and likely explains why Serviio doesn't list a rating for it. When I check themoviedb.org, which is where Serviio retrieves its movie metadata, it is listed as Unrated. Upon further research, I see the MPAA started rating movies in 1968, much later than I thought. I did find a movie made in '86 that shows a PG rating, but Serviio has it as Unknown.
But as to your question about TV-MA, I may have found an answer. When I looked at thetvdb.com, I don't see any ratings for any of the shows I looked up. So there's no such data available for TV shows. For movies that are played on TV that you might record (I have 650 movies I have recorded OTA), Serviio is only going to have the rating assigned for a theatre showing, so a rating like TV-MA simply isn't available for retrieval.
