Is there an efficient way to tell if a rubik's cube state is 2-gen?
If there is a 2x2x3 block anywhere on a 3x3x3 cube, then I believe it can be solved in 2-gen.

do an a perm and see if it works
Sorta, not really though.
Check if CP is correct. And all edges must be oriented. Check if by only doing the 2gen moves, that all the unsolved pieces can be moved into their correct spot (aka any pieces untouched by the 2gen moves must be solved)
Walter Souza, define what you want to mean by 2-gen. <R,U> is 2-gen. <M,U> is 2-gen. <RUR'LDF,L2B> is 2-gen. If you mean 2-gen in the broadest sense, I don't think there really is an efficient way to check.
is lubixcube.com safe and reliable, also how good is the shipping?
Yes, reliable. The shipping depends on which country you live. To UK it takes 2 or 3 weeks approx.
whut?2gen Aperms exist FYI. So your example is still solvable 2gen.
in roux method, for the F4 case, I got an alg:
U²
B’[RUR’]
B (RU’)
BR’
and I couldn't figure out a way to go into the 2nd B turn without regripping, can anyone help me with this?
I find this is a really fast alg until that 2nd B turn
