I don't think they are all immune to electricity. Milluki doesn't seem to display the ability to resist torture at all. I think just like Nen, their father/grandfathers also think of the best type of ability to train their kids with. And it also looks like not all family members know what abilities other members have. Just like Killua doesn't know his Illumi's ability and he seems oblivious about Kalluto's ability to use nen.
