Is there a rayswitch functionality for Karma (xpu)? I can't seem to find anything along those lines.

There is rayimport and a switch node, up to you to do what you will.

How would I recreate the effect of arnold/redshift/vray rayswitch with this? I would like to have a blue cube that reflects red, refracts green, bounces of GI pink.

I haven't found a ray style import, so that's not possible that I know of. It was possible with mantra since it can import the ray level for each style separately. Karma ray import has "level" which will tell you which bounce the ray is on, but not which bsdf is sending the ray.
