Number of myths floating around here...
The UK was NOT dependant on the US or L-L to defeat the U-boats. The U-boat campaign was basically won in 1941 (the heavy losses in 42 were mainly due to the US not learning the lessons). Ther US involvement during this period was pretty much zero - 50 pretty useless destroyers (which had to be pretty much rebuilt), some short range MPA, thats about it. US merchant ship production was well under that of the Empire at this point.
So Britain can only be starved out if Hitler puts back Barbarossa (and maybe not even then), which will make Stalin very happy.
Basically Hitler cannot force the UK out of the war (even if he devotes all his sffort to it) before 42-3 at the EARLIEST. Meanwhile Russia is just sitting there getting stronger and stronger....
There is also the issue of L-L. Nothing much reached the UK until the 1942 (by which point the US was in the war...). Now a neutral/isolationism President might well not pass L-L. However not allowing cash & carry is much more difficult to believe - the USA was still in recession, C&C started/helped pull it out. Explaining why US voters are sitting there without jobs because of high moral principles isnt exactly going to go down well.
The biggest advantage Hitler gets from a not-interested USA is the greater chance of Britain negotiating a settlement (would would also mean he'd have to settle one with other countries like France as well....). At which point even Stalin realises hes the next target. And given the circumstances, Britain can sit there and hold out for a white peace, they know they are actually in a powerful position. The Channel is such a useful piece of geography....
