Can the sludge monster engines break down synthetic oils like Redline, Schaeffer's (part and competely synthetic), Mobil 1, Mobil Delvac, and Amsoil? Will products like Auto-RX and Lube Control be able to help prevent the break down of the oil?

It takes a bit longer but yes, the sludge monster engines can turn true synthetics into sludge also. You simply cannot do extremely long (15k+) oil change intervals with these engines. Don't go over 5k with any synthetic oil in these engines without a UOA. And definitely don't go over 3k with dino.
