Yes, yes they do.
I believe it's: Butter, Lesser, and Vin Russo that are all het for BEL and will produce them when bred in any combination between them. Then you have Mojaves and Phantoms which both produce very distinct animals when bred to themselves but BELs when bred to the other 3.
Outside of those 5 I don't know of any other Blue Eyed Leucistic forming snakes.
