Like you say, without a direct sample of Lutetia, no one can be absolutely certain. On this I agree. But for me, all signs are pointing towards ---> enstatite. If I were to place a bet, that's what I would be betting on. In the case of Vesta, it was predicted that it was the source for HED's through Spectroscopy long before the chain of Vestoids was found spanning along Vesta's orbit. Granted, Spectroscopy of asteroids from Earth is probably not as accurate as from a space probe in a close flyby. But that's one of the reasons why it's nice that we have Dawn and Rosetta now.
