Isn't the word you're looking for here TAILERONS ? Or is there yet another one? I actually never was aware the Raptor featured those. So are there no ailerons on that jet or is there both? The latter would seem to be a lot of moving surfaces during flight for a VLO jet. Even though it's a bonus for agility.

Scratch, the F-22 was designed to be the very first "super maneuverable" fighter in regular production, The flapperons, stabilator, (defined as an "all flying tail", as opposed to a horizontal stab/hinged elevator), (hence my "stabilons" in the interest of accuracy) are wired through the FCS to provide assymetric operation to enhance roll rates, that same FCS uses the 2D thrust vectoring in concert with the control surfaces to further enhance pitch and roll rates.
There are separate flaps and ailerons, and both are controlled by the FCS for assymetric function, as are the 2D nozzles, which at supersonic speeds are commanded by the FCS to be the primary controls as one hand flies the aircraft, as stick application increases, then the control commands bring in the control surfaces, that cuts trim drag, as well as RCS spikes.
The T-50 is very much the same, with the addition of 3D OVT and LEVCONS, and the J-20s control surfaces are also perform those same function with the addition of canard to enhance pitch rate.

I'm aware of the difference and utility of stab+elevator vs stabilator or all flying tail. My point is, a stabilator works in a unified fashion, i.e. not differential, hence can only control pitch.
When those stabilators become capable of differential deflection to controll pitch & roll, like on a Tornado, F/A-18, modern Flankers, Raptor, they are now Tailerons, or "rolling tails".
Or Elevons on tailless airplanes.
I'm not sure if I'm missreading you here, but I'm fairly certain the TVC nozzles are not capable of differential deflection and thus only contribute to pitch control, but not directly to roll control. I believe I read that somewhere, but right now cannot find something definitive one way or the other. Anyhow, I think the engines are to close together anyway to be meaningfull contributers to roll.
What that TVC does for roll is that by taking over pitch authority, it frees the tailerons of that function to let them focus on rolling the jet.

The pilot's will released them once they are in range of enemy radars to get back on their stealth mode. When your radars are better than the other guy, one can afford to have the extra drop tanks for further traveling therefore saving the internal fuel for the dog fights and bombing mission.
