Moral of the story - don't buy a used BMW from an Audi dealer.
A few things: did you not drive the car beforehand and notice that the car had 'horribly warped rotors'? This is something one can usually deduce from a test drive. Two, they are wheels, not 'rims'. What the hell is a 'rim leak'?

Rotors rarely warp, it's most likely brake pad deposition, on the rotors themselves. Rotors simply don't "warp", like the old mechanics used to say they did. There are several tests out there to prove this theory, so I'll leave that out there. To suggest that a warped rotor caused premature wear on a caliper, makes absolutely no sense, though, no offence. How do you know there is a caliper issue, did they provide a diagnostic report? Is this an M-Sport Brambo brake system, or standard 1-piston sliding caliper? Reason I ask, is, the 4 pot Brembo's are almost indestructible. The single piston style caliper can start to "seize" due to lack of lubrication on the sliders, causing poor braking performance and premature PAD wear, but is still fully serviceable, and able to be "repaired". When it comes to "safety" most jurisdictions regulate safety based on minimal specs of remaining materials. So if your rotors are within OE spec, for thickness, along with your pads, they can be considered "safe" from an inspection standpoint, performance and feel notwithstanding, of course. Buying a non-cert BMW, from Audi, with upwards of 50 thousand miles on it, I honestly wouldn't expect much... The best time to resolve these concerns is to have them include new brakes, tires, etc with the sale deal, to avoid near future frustrations and potential early ownership repairs.. I learned this early in the car buying game, my first car was a pre-owned high km VW, and yea, it sucked  Parts were cheap, though

Just replace. Go to a place you trust and diagnose if it's the wheel, tire, or valve stem and replace the part needed. You can try to get the seller to cover the cost of parts, but even then we are not talking so much - maybe $300 ball park if there is something wrong with the wheel.
A used car bought as-is is just that. They may want to satisfy you for good will purposes, but they don't have to do anything really. As for the brakes, same, have a third party inspect and if the pads and rotors are within spec, just buy new pads and factory BMW rotors and replace them yourself and move on. Not too expensive either. If they are out of spec bring that to the attention of the seller and see what they want to do to satisfy you. I have no idea what is meany by warped rotors causing premature wear on calipers. Calipers don't wear. They either clamp and move freely without leaking or they don't. Only pads and rotors "wear". BMWs can be tough on rotors. I have had issues with brakes on my BMWs with aftermarket rotors, even Brembo brand and proper pad bedding procedure. Now I only use BMW parts for the rotor and have never had any issues at all.
