Those transmission-to-engine bolts do not seal in any oil. In fact, there are holes in the bottom specifically so any leaking engine oil or transmission fluid will run out and not back up inside there. The most common cause of an oil leak from there is the rear main seal, but they usually do not leak that fast. In this case it is more likely something up above that area is leaking and running down. Oil is not going to leak from the engine when it is not running, unless the oil pan is rusted through. If you are seeing drips long after the engine has been stopped. That is due to the oil pooling somewhere and slowly sneaking through a small opening to run out. Look for the highest place you see oil in that area. For oil to leak really quickly, common causes are the oil pressure sending unit and a threaded or pressed-in plug in the engine block or cylinder head.
Also, look at the valve cover gaskets. Oil can leak from them real fast too but slow leakage is more common. If regular maintenance schedules have not been followed, it is possible for the oil drain-back holes in a cylinder head to be partially blocked with sludge. That will cause the oil to accumulate up there. That will turn a small valve cover leak into a big mess.
