To the best of my knowledge and belief there is not an equivalent in any US carrier (again I am talking transatlantic) they have a Purser but the title means that they get to do all the paperwork and bar counts. They have no management authority over any of the Flight Attendants and can not give them any instructions. Thus they are paid for responsibility but have no authority. They have serving duties - usually in F.

DL has OnBoard Leaders, or OBLs. On domestic routes, its a meaningless designation, simply doing the bar counts and handing in the paperwork.
For their int'l service, these individuals do seem to be more of a manager/orchestrator during the flights and do in fact direct the other FAs to particular tasks.
