LIFUS is line training effectively, so a rated pilot learning to operate the aircraft, mainly used in airlines.
A TRI restricted to sim only can do just that, sim only. Further training is required for LIFUS. If you want aircraft privileges such as non-normals, type rating (base training) then you will have to pass an AOC with a TRE who also has those privileges on the aircraft.
If you have both, revalidation can only be achieved for both with a single aircraft check or a sim and aircraft check.
