if the roots were damaged and it stalled immediately afterward... maybe.
on its own, no LST is not why your plant is short other then the physical bending of the plant but growth should be similar, but spread out.
You should have some vegetative growth left in her... it'll continue to grow for a bit while it initially flowers.
did it ever seem to stall while growing? if not, it's just genetics, becauase those leaves look healthy AF. Maybe light was too intense? you ahve super close nodes, but that's typical on a smaller auto i guess.
I bet it stretches more..
