While I admit there's a momentary bolt of lightning in one scene, judging from the subsequent application of the technique, it still doesn't contain any lightning at all. What's more important, lightning bolts can be seen even in the techniques that don't include Lightning Release, it's just a part of their animation to show the chakra concentration - for example, during Itachi/Sasuke vs Kabuto, in the scene with Sasuke's trying to shoot an arrow in Kabuto, his Susanoo is momentarily surrounded by lightning when Sasuke advances it from the sceleton to the humanoid stage, although it's been established that Susanoo is a non-elemental jutsu (techniques like Susanoo: Chidori don't count since they are separate techniques with Susanoo used as a medium for them).
