YES....LG puts that pinch in the cap tubes from the factory.
From what Ive been told, they put that pinch in there so you don't hear the sound of refrigerant flowing/equalizing during the off cycle.
Lg said to remove said pinched area and that should take care of the restriction.
That was me talking to LG tech support a few years ago. Idk how i even made it that far because you're supposed to be factory authorized...etc...blah blah blah...
He said on some units they over-pinched that area and caused too much of a restriction OR something gets stuck at the pinch causing a complete blockage
