Welcome to Android Central! It's a false positive. There have been other threads about this Verizon APN library system app on non-Verizon phones -- this kind of thing has been known to occur on various phones (including Sprint apps on an unlocked phone). It's most likely because the manufacturer wants to make sure the phone will be able to operate on Verizon if the owner decides to switch carriers in the future.
