If photons are emitted or absorbed when a pair or a collection of particles, that are or behave as dipoles, undergo oscillation by some driving force, are there any systems that do NOT use a single or collective dipole oscillation to emit or absorb a photon?

no charge moving no photon as it seems to me.

All multipoles (other than monopole), quadrupole, octopole, etc.
can emit and absorb photons.
