Personally I think Larian should fix that you use the last class you picked for items and scrolls. Of all the possible options this is the one that makes the least sense.
Every other option I can think of would make more sense:
1. The class you picked first
2. The class that has the most levels
3. The attribute thats the highest bonus
4. The attribute that relates to the spell in question - if you use a Cleric item, it would use Wis, etc
But the last class picked makes no sense to me. For example a Bard(11)/Cleric(1) that started as Bard and scores a Charisma 20 score, but only a Wis 13 score (thats original D&D5 rules for picking up a Cleric multiclass, not enforced in BG3) and picked up Cleric on level 7 to afterwards continue with Bard, should absolutely use Charisma not Wisdom for scrolls and items. This is primarily a Bard in every regard.
