You can always install a mod to get randomness if that is your preference
And you can always install a mod to get hand placed if that is your preference.
In fact, there are actually plenty of DOS2 equipment mods that do provide hand placed loot.
Meanwhile, there are far fewer mods that provide random loot for BG3 (If there even is one... I haven't seen one so far, though I haven't looked exhaustively in a while. Every item mod I've seen is handplaced or shoved in the Tutorial Chest)
