[Mass Effect/Star Wars] Can Biotics be used to throw lighting? Would it be possible, using Mass Effect universe resources, to build a lightsaber?

Throwing lightning wouldn't be accomplished with Biotics. It's like asking someone to throw lightning with a pneumatic cannon. The closest you could get would be an extremely insulated hardsuit and a man portable Tesla coil giving you highly limited range, poor accuracy and probably damaging whatever electronics you have on you.

As for a lightsaber, the closest you could get is probably some sort of plasma cutter. But more importantly why bother to make one? Long range is dominated by hypersonic projectiles which means you aren't going to be blocking anything and even if you could the great big plasma cutter will be using far more energy than a kinetic barrier for less protection. Maybe it has some utility in melee range but there are already options for that.
