[Star Wars] Why didn't any Jedi bother learning force lightning or some variation of it during the Clone Wars?

Fighting armies of droids, that would seem to be pretty useful. And in KOTOR/KOTOR II, there were non darkside abilities to disable and destroy droids with force lightning, so why didn't the Jedi even try doing that?

Force lightning is hatred made manifest. You project your hatred as a weapon to destroy your enemy. That isn't just philosophy, either; it's the mental state you need to be in to generate lightning. Rather unbecoming for a Jedi.

In Legends there are versions of lightning that don't require diving face first into the dark side, but during the Clone Wars specifically its use was forbidden by the Council.
