Paleoveneti is another name for the Italian Veneti, maybe you could use that? Homer is believed to have called them Eneti, a Illyrian tribe that migrated into Italy. So either name may work better.
Libyans would have a wide range of troops and types. Mods have had them with 4 horse chariots. They were known to have invaded Egypt as part of the sea peoples invasions long ago. In origin, the Libyans are believed to have been a colonizing Greek Tribe called the Libu who probably intermixed with local tribes like the Temehu. When they worked for Carthage they could have had anything from heavy infantry and light skirmishers to heavy and light cavalry. In ancient times they were known to use swords (some of which may have been copied off the minoans or Philistines), spears, the Meshwesh sure had some distinguished spears (another native tribe of Libya), and chariots, that could have been carried over from Greece if that story of their origin is true and it is probable it could well be, or Egyptians.
