I don't think it is possible to change name in interline booking. Your best bet is to have DL and VS document your son's nickname and real name in the PNR OSI or memo field. I don't know how VS will deal with TSA APIS for return segment.
Depending upon the airlines involved, this is basically correct (certain airline combinations are able to adjust things like this). Even a correction of two transposed letters is a problem. Not sure why OP would even think that the correct name was not important. Could well be an expensive lesson for the OP to learn. I don't think OSI's in the PNR will help as TSA and various immigrations agencies don't have access to that information. Those are the people that count.
