2002 Deville DTS Towing Capacity
My parents have a 2002 DTS; I was amazed to find out that the towing capacity is only 2000 lbs. Why?? I thought people use these things to tow large trailors. With a 300 HP engine, this top of the line car should be able to tow a house. Is anyone aware of any aftermarket tow packages that would enable the car to tow more and not invalidate the warranty?

Not sure of your understanding of trailering requirements and such but just because a car is the "top of the line" does not mean it was designed to tow heavy loads. Trailering capacity is very limited on many many vehicles.
You can tow with the DTS but the capacity of the car to tow anything over 2000 pounds is very limited.
Understand that when a manufacturer validates a vehile to tow heavy loads it is always done with the worst case scenario in mind...i.e...the assumption is always there that an owner may very well put the maxiumum capacity trailer load behind the vehicle already loaded to GVW and then head across Death Valley in the summer and try to climb the steep grades to exit Death Valley. So trucks and such that are rated to tow 10,000 pounds or so are tested under those conditions to validate the performance of the package...and much heavier dury radiators, cooling fans, trans coolers, oil coolers, etc. are all engineered into the package to allow the vehicle to successfully tow under those extreme conditions.
If you use some common sense and limit the load, speed, etc. of the trailer the vehicles can often tow much more than the limitations put on trailering by the manufacturer in less stringent conditions...i.e...the car can tow a lot more on a 70 degree day than on a 110 degree day without overheating or having other problems.
The Cadillac FWD cars also have other limitations in the transmission in the form of the VCC used to lock the torque converter. The viscous converter clutch (VCC) always creeps or slips a tiny bit to eliminate the driveline pertubations called chuggle...the rough feeling to the driveline when the torque converter locks up. Towing a trailer can cause excessive slippage in the VCC over long periods of time causing heat build up and damage to the torque converter and trans.
There are trailering packages available from GM for the Cadillacs that consist of heavier duty radiators and oil coolers for the engine. It would appear that the car in question was not equipped that way so the original purchaser must not have had trailter towing in their plans.
The 300 HP engine is to provide adequate vehicle performance...not to tow large loads on trailers.
