Back to the switch in question would a 220 VAC 15 Amp switch be able to handle the load. The VFD would be shut down during switching operations.

Yes, a 15A rated 3 phase switch will be plenty for the 1.5hp Tormach motor (each phase carries about 7A at full load).

You are not the first to do this; there is at least one other person on this forum that installed a 3 phase switch. There also used to be a product on ebay which was a switched USB socket, which would allow you to easily reprogram your VFD when making the switch from mill to RT.

I have that. It was made by Mill Fast and works great. The PITA is changing the motor cables, even with the so-called "quick change: device. Seems that had Tormach equipped the RT with a 1.5 hp motor all the hassle might have been avoided. And I suspect those Chinese horses are more like Shetland ponies than Drysdales.
