Do orcas engage in an equivalent of intertribal warfare?

If not they might not even have instincts for group defense or retaliation (except in the context of one off encounters with predators).

Not all-out warfare but there can be inter-pod skirmishes. They also hunt in groups and communicate the movement of their prey to co-ordinate their attacks together.
