I’ve got to say that I miss read the original logline as well, this is probably indicative of a flaw in the logline. I think best to re visit the wording at least to emphasize that the boy is not recognised as the Dalai Lama but as another spiritual leader.

That said I don’t think the stakes are high enough, the Dalai Lama is the spiritual leader of billions his significance is imminence. The re incarnation of a monk would be far less a “big deal” and therefore presents less of an obstacle for the boy to adapt for.? Would this be as interesting as if he were as the spiritual leader of billions of people and recognised around the world?
The facts of a true event shouldn’t stand in the way of a good story, and if you’re trying to tell the story of a delinquent adapting to a sudden change and new responsibilities then perhaps greater stake would make for a better story.
