Currently 2D as al AL-31/41, in the future of course a 3D TVC would make a lot of sense for a single engine fighter and I would not be surprised if they are working on it.

That's some sort of brain masturbating here.
No, Su-57 has 2D TVC engines, they achieve the pseudo 3D effect by angling and differential deflection of the nozzles.

Did it say anything about the F-117? They just refer the izd. 117 from what I see.
F-117 BTW was a very rudimentary stealth plane and the science and technology have come a long way since then. I see no fundamental sin in the LTS that prevents it from being a very low RCS plane at the frequencies where current technology is effective.
EDIT: it seems they refer the F-117 in the patent as an aircraft that got stealth at a significant cost in other regards, but it is logical due to the prehistorical level of computation at the time.
TASS has these news about the LTS patent:
