The fact that a mere residual emission from Valkorion's FLS was potent enough to breach defenses of a military-grade starship mid-flight, should tell you something about the intensity of the FLS on the whole.
Where's your evidence that they were shielded, and if they weren't, how do we know their hulls were particularly insulated? It's not like they were expecting to be fired upon by lightning.
Force lightning cannot breach defenses of a military-grade starship easily. Lord Vindican attempted to breach defenses of the starship of a smuggler with Force lightning but it didn't work, and his Force lightning was intense enough to hurt Darth Malgus.
Vindican and the Malgus in the trailer are both weaker than Valkorion, yes.
Now if a starship faces the the full brunt of Valkorion's FLS, do you think it will remain intact? No.
It probably depends on the starship. But plenty of things that can breach the hulls of a smuggler's ship cannot phase a lightsaber blade.
