It's not unknown for single-engined aircraft to have the engine thrust line (and/or fin) offset to counteract torque, but it's normally only by a couple of degrees or so, and very difficult to detect visually.
I'm not aware of any multi-engined aircraft that have this feature, though I stand to be corrected.
There's a good hi-res photo of the Saab 2000 from underneath on Wikipedia Commons, if that helps:
