vtkMapper::AddClippingPlane and picking and highlighting are working now as
expected. However, I'd like to achieve the same clipping functionality as
"InsideOutOn" in vtkClipPolyData. Is there an equivalent property such as
"InsideOutOn" in vtkMapper when a clipping plane is added? I know I can
probably invert clipping plane normal to achieve this, but thought there
might be a nicer way to achieve this.

There is no InsideOut equivalent, it is necessary to flip the normal.
