In Total War: Attila there are axemen units that will throw their axes en masse as a tactic, is this based on historical evidence?

Procopius states that the Franks would hurl small axes at their enemies just before they closed for hand-to-hand combat in order to shatter shields, kill soldiers, and disrupt the formation, so kind of, yes.

You might also want to look at Richard Underwood's Anglo-Saxon Weapons and Warfare for more information (he also references Procopius)
