Bones probably don’t conduct electricity all that much so that should help Lightning. I can’t say that I know much about bones though. Kimimaro is very fast in his awakened form and he might surpass Lightning there. What will help her fight back is Lightning’s array of spells and elemental attacks. Kimimaro can’t carelessly rush her or he’ll get hit and staying from afar will be dangerous as well. Odin might be a little less useful here than usual since he’ll have a tough time landing attacks but every bit helps. I think Kimimaro just doesn’t have enough attack options here and Lightning certainly has more combat experience. Lightning wins.
