Little League is the same as OBR in this instance. The plate umpire is required to ask for help if a checked-swing called a ball is appealed by the catcher or manager. I'll have to dig up my copy of Little League's casebook. I have one somewhere, and I do not believe anyone at any region is teaching that a checked-swing appeal is optional. I haven't worked a Little League game all year, so I'm a bit out of the loop, though.
