No, it is not even technically possible for an item with an effective level for legendary potential of 100 to drop 4 LP. You will NEVER see a legit Ravenous Void for example with more than 1 LP. I'm not even sure 1 LP is possible on that item...
No, it is technically possible for Ravenous Void to drop with 4LP. It's just so rare that it's not practically possible.
