This is correct. The Amber force field has no notion of dipole moments for
pairs of atoms, although I suppose you could calculate such quantitites
if you wanted to.

For a neutral system, the dipole moment is independent of the origin. For a
charged system, the center of mass is one possible origin. Again, this is not
part of the force field.
