A.T. Robertson Commentary Luke 23:15

"no, nor yet Herod: for he sent him back unto us; and behold, nothing worthy of death hath been done by him." — Luke 23:15 (ASV)

No nor yet (αλλ' ουδε). But not even.

Hath been done by him (εστιν πεπραγμενον αυτω). Periphrastic perfect passive indicative of πρασσω, common verb, to do. The case of αυτω can be regarded as either the dative or the instrumental (Robertson, Grammar, pp. 534,542).
