Well, I couldn't find two (and even some more variations) slightly different LL states (and therefore substeps for the LL) on the map, so I thought I could post them here:
One is to do a second face after the F2L (as the state after the R F U R2 U' R F' R U R' U' R2 scramble does, it's 107 algs) and then solve the rest (another 142 algs, I would call it the 2 faces last layer ''2FLLs''). However, if you do VHLS beforehand, you're only left with 53 and 35 algs, since EO is already done (let's say O2FLL for that) !
On the other hand, you could directly build a 1x1x3 Block on the LL (like this : R U' L' U R' U2 L F U2 F' L' U L, but ... it's 215 cases), nevertheless there will only be 70 cases of these ''BarLLs''. Like for 2FLLs you can also do VHLS first so you would only have 35 and 50 cases to learn, which is already an affordable method (OBarLL).
Finally, if you combine this 1x1x3 bar with the 2x2 block on the LL, you get some kind of Bar-Block states (as for : U R2 U' R' U F' U F U2 R U F R F' R2 U' , AND, could there be a possible 3LLL method ?), there are 19 of these ''BBLLs'' (of which 8 have EO done).
