Agenda 2020 allows host cities/countries to add a few sports they want to grow locally, or that are popular in the host nation.
Lacrosse isn’t a bad candidate as it does have a good audience in the United States. It’s not all that popular on the West Coast though (it’s more of an East Coast thing).
Personally, I’d like to see Skateboard, Surfing, Sport Climbing, and Flying Disc (Team Ultimate) added to the program under that clause. I know there’s been movements to add Lacrosse, Cricket, Baseball/Softball, and Cheerleading (among other sports) as well.
