I know you are upset about losing the engine and all the expense, but you need to be fair to the Volvo guys too. Now whether or not that engine actually used a quart every 800 miles is one thing, the engine is toast now so no way to verify. It does sound like a bit of an exaggeration, but older motors using about a quart every thousand miles is not too out of the ordinary. Add to that a small oil leak, and running bone dry in 3800 miles is quite possible
The thing is, why didn't you notice any warning signs well before the engine was destroyed? The purpose if the oil warning is to let you know when it is becoming low on oil..or if there is a problem with oil pressure. This way you shut it down and find out what is wrong before causing catastrophic damage to the engine. It doesn't wait until it is bone dry, then come on when the engine fails, it should indicate when the pressure drops, not wait until it is bone dry.
There have been studies that show a car can in some cases can run for quite some time without oil, but there will be signs such as noises and lights/gauges/warnings indicating no oil pressure.
Now if this vehicle did use that much oil...at about 3200 miles you would be down 4 quarts...less then half capacity. Surely at some point you would have heard the lifters tapping and see the oil warning, or some indications. The engine will suffer low oil pressure when you a getting low on oil, not just at the moment when it runs bone dry.
I don't think leaving the "lid" off would dump over 7 quarts of oil..it would just splash out a little at a time and you would have seen a ton of smoke and smelled oil burning as it leaked onto the hot exhaust manifold. It would have been an obvious mess with plenty of tell tale.
If they had left the drain plug loose (which is under the engine and used to drain the oil during a service), it is possible you could over time lose all the oil..as well if it just had a leak such as a bad oil pan gasket or fitting. These can develop at anytime. The palm size stain where you park can indicate an oil leak, but it would have to be a slow leak because if 7 quarts had leaked at once, it would have looked like a mini Valdez under the car.
Either way, it would be really tough to prove if this was negligence on the Volvo mechanics part because you claim you drove almost 4000 miles since your last maintenance so it is not likely they will except any blame. If they actually had left the drain plug too loose, you probably would have lost all the oil at one time if it came undone and the warning message would have came on giving you time to shut it down and save the engine.
If the oil was leaking slowly which seems more likely the case, there had to be some tell tale signs you were ignoring..do you recall any tapping noises or warnings, or any indicator lights come on, or was it running perfect with no signs of low oil and just all of a sudden you heard a strange sound, the warning came on and the engine failed? If the latter is the case, I would suspect there was a problem with the oil pressure sensor as well, because as stated, it should indicate when it is starting to become low on oil, not wait until there is zero pressure and the engine is destroyed.
Of course if something gave and all the oil came out at once you would have had indication, but if you drove too long without oil, it will of course destroy the engine eventually and it is hard to blame anyone else for that. If this had happened very soon after an oil change (within a day or two), then it is much easier to blame the mechanic if it was due to the oil drain bolt or oil filter not being properly tightened.
As far as the dealer being overpriced..this is no news. I only buy my parts from the dealer if it is not available anywhere else. Dealer parts can be 3-4 times aftermarket replacement cost, and their labor rates can easily be double of an independent shop. Yes, the dealers are a rip off in that sense, but if a vehicle is out of warranty, the good news is we are not forced to use them for repairs in most cases.
A Toyota dealer charged my father over $2000.00 to replace a leaky valve cover gasket. He lives on the other coast but if I was there I could have done it in 3 hours at a total cost of under $30.00 in parts.
