welp i got a C32
Would it make more sense of me to pay 400 and get it to my house and fix it all myself or pay 1125?
I flew up to Orlando to pick up my C32 and driving it home the supercharger pump was shot. I know whats its like to have big expectations of a new car and be completely let down. Turns out the previous owner knew nothing about the car and only changed the oil in the whole year he had it. So I feel your pain
I think it is very unlikely (though not impossible) for pulley #6 (supercharger guide pulley) failure to lead to failure of #9 (tensioner).
In contradistinction, a problem with #4 (idler pulley) could lead to seizure and downstream damage to #9.
The idler pulley (#4) is bolted onto the water pump housing. If pulley #4 breaks or the bearing seizes, the water pump housing can be destroyed.

In answer to your question though – tough call.
Are they going to charge you anything for what they’ve done already?
As costly as it might seem, $1125 might not be so bad considering the cost of parts + your time + towing the car home versus having the dealer take care of it.
On the other hand, if you'd rather some face time with the M112K, tow it home and do it yourself.
