Well they are right and wrong. Toyota does not authorize them to do the warranty repair until they've verified the problem exists. Toyota also doesn't authorize the use of the new ECU firmware without the new CATS nor (apparently) the CATS without the ECU firmware. Your dealership service shop performed a modification to your vehicle which is not factory authorized. This information could be used by Toyota to deny future warranty claims.
If you weren't charged for the repair, then you dealership billed Toyota. In that case they did so without actually performing the repair they billed. That's called fraud! I'm sure Toyota would be glad to know about it. The dealership manager would probably like to know too. In short, you've got them by the balls in more way than one here. There's only one way out that doesn't cost them anything and that is to finish the procedure.
After they do the CATS make sure they redo the initialization/calibration step documented at the end of the TSB. Or, if possible, make sure they just do the whole thing over.
