I would not tolerate DLC with no squad banter (Omega *ahem*). That's probably why I won't buy any ME2 DLC.
As Restrider said, you do get some good banter with Liara in LotSB.
I didn't really notice the lack of banter in the other dlcs much, but there are a few slightly odd moments when the camera turns to a squadmate, and they just give a mute reaction shot. In Arrival it's quite noticable that Seth Green wasn't available, as Joker doesn't have a thing to say while the camera focuses on him as he's frantically piloting the Normandy away from the explosion.
But like I said it's a very minor thing. The dlcs were all very enjoyable regardless.
