Say I DM a Storm King's Thunder session for Adventurers League. In this hardcover, there are multiple instances of having to randomly distribute magic items. The instructions are as follow:
Sometimes a treasure hoard contains one or more magic items determined by rolling on the magic item treasure tables in chapter 7 of the Dungeon Master's Guide. When determining a random magic item, roll a d100 (or have a player roll for you) and consult the specified table in the Dungeon Master's Guide. If your players have a "wish list" of magic items, or you think a particular item might be useful to the party, you can forgo the roll and select an item from the table.
Now what would happen if I were to roll a 10 on Table F, which says Weapon +1? It can be any type of weapon, but there are no tables for randomly choosing the type. Is it okay to choose a type that would be useful to one of the player at the table? Maybe ask everyone for their prefered type and roll between those?

According to the Storm King's Thunder Adventurer's League FAQ:
So you must roll randomly, but you can indeed pick a type of weapon that suits your party.
