Indeed !It might be "Adventure League" but they typed a small L by mistake?
The detail about A.I. GMs was supposed to read AL, Adventurer's League, Al looks like A.I.,when the text auto corrected. Sub the statement with "AL" and it makes a lot more sense. A.I. only sort of makes sense because of its current popularity and more recent use in the context of limiting "A.I. GMs" to a more stripped down version of One DnD access and content.
I don't mind being wrong here, but how many A.I. GMs do you know or have seen lately? Also, that information could have been drafted months before the leak, in which makes even less sense based on the context here. It looks like our community might also be confused by the leaked info due to one small auto correction. Ai vs Al.
