I am asking you: What if the sun put out nothing except
EM waves. Would comets still have a tail or not?
Are you talking about the ion tail or the dust tail? The dust tail is
affected by EM; but the ion tail is affected only by magnetic forces.
So a large part of the visible tail of the comet would
still point away from the sun even if the sun emitted
nothing but EM waves. EM waves possess momentum, apply
radiation pressure to dust particles (matter), and have
relativistic mass.

That is correct.
