My guess is that the kid was taped by his agent, who sent the video to the casting director. The British accent is something generic for foreign characters. The production may have just wanted to check if the actor could master at least one accent, then he would have been coached for a German one. Once again, pretty generic stuff, that hundreds of child actors around Los Angeles tried.
That said, they may have also used the tapes to cast Yorkie, Johann's best friend in the movie.
Hoffman does a great job - that's why he's revered in the biz.
