Cannot feed #2 4 conductor wire through 2" PVC LB box without high force effort which divots the insulation

There is no reason 4- #2's should be any problem in 2".
How are you doing this? Please don't tell me you are trying to pull them through the LB.
Are you pulling a big loop out of the LB and then feeding them into the other side?

What kind of cable?

Aluminum 4 conductor SE? Maybe. My guess.
