I don't think its possible for Larian to make BG3 solo-able without removing parts that make this D&D and not divinity. Unless they have the tech built in to adjust ALL enemy encounters to a single player game...I don't see it happening because a single PC just isn't strong enough, no matter how min-maxed. With a level CAP of 10, you are going to see monsters/enemies up to CR 11-14 most likely in the bosses. For a single PC, a CR 5 monster is technically a medium difficulty. A CR 10 monster, in most cases, is impossible for one PC. And since they have built the entire game and there are no random spawns, I don't see them being able to substitute to account for a single PC.
You are also forgetting that PCs have a thing called planning, metaknowledge and strategy. Malavon is considered one of the hardest IWD bosses and here is i soloing him with no damage on max difficulty.

That is a HUGE problem. Lv 81 necromancers should be using expert/master frost destruction spells, have a army of undead, among a lot of other things. Buffing only health and damage is the worst way to make a mob harder. Having high level enemies feeling more like spell/arrow/strike sponges instead of powerful enemies is not good.
Even Diablo 1, a very streamlined game from 97, enemies casts different spells, are in different levels, has immunities and resistances, attack ratting and armor class, etc; on hell compared to normal.
