Besides Tela Vasir and Shadow Broker himself, the DLC didn't have any technically new enemies, only the reskinned ME2 heavy, engineer, vanguard and soldier templates (the latter did have Flashbang Grenades added in, though).

Well, yes, but it did have the car chase sequence, and the fights against Tela Vasir and the Shadow Broker were quite unique, so I'd say those count.
