Sorry to hear this, but your problems are not uncommon with older TW's where someone has already boogered up all the JIS fasteners and over torqued the drain plug resulting in diificulty/damage trying to remove it.
I doubt if you would be very successful in trying to suction the oil out. If you take your fill plug off and look down inside the side cover, you will see a bunch of gears and hardware that would prevent you from passing a tube to the bottom of the engine where the oil is. Even if you could get a tube past all that stuff, you could only access the oil that is in the side cover and not what is in the crankcase and the other side cover.
I agree with Ski, You should order the new parts that you would need and do what it takes to remove and replace the damaged parts.
I suppose it would be possible to drain your oil by inverting your bike, but I wouldn't really recommend that approach
