I seriously doubt that they would go after Jellal or Ultear for several reasons:

-They are all forever wandering so its not like they would be able to find them easily. -Both Jellal and Ultear nearly destroyed the MC and are considered enemies of Fiore, and because of that they aren't a threat to Tartaros -Tartaros is probably hunting down former members so the MC cannot rebuild itself, either that or so they cannot fire the etheron cannon that everyone forgot about. -Ultear is gone from the story, she is finally "redeemed" and now will live her remaining days in peace, that or she died on the road we saw her on, so Mashima won't bring her back and if he does, we will see her die. -Jellal is a escaped convict as well as a former MC member so because his location is unknown whereas most of the other former MC's have a home, they won't hunt him and because of the convict/traitor of the country status he has as stated above, they are not going to target him........unless he fights against them which he will.
