The level 2 transmutation spell "Knock" negates the need for lockpick and even opens magical locks/barriers for 10 minutes. The only caveat is that "knock" creates a HUGE audible knock sound that can be heard for 300ft. Sneak and lockpick are functions of the rouge and they always have both skills by default. Any other class wanting to perfrom these skills normally muct sacrifice something potentially more valuable to their specific calss attributes.
The rouge using the arcane tricktser subclass is a master at avoiding traps, opening locks, stealth etc. using a combination of skill and arcane magic. Currently the arcane trickster in BG3 is missing half of its kit and spells. His mage hand can pick locks, pick pockets, disarm traps and he/she can use knock, invisibility, greater invisibility etc.
As far as I am aware (unless it changed) scrolls are class AND level specific and not "generic" spells anyone can cast. There are exceptions, at 13th level the generic rouge gets the "use magical item" skill which allows them to decipher and use spells of any calss or level. There are other classes/subclasses that can use them this is just an example.
I mean these rules are ok for EA as you can only get to level 4 but later on to levels 5-6-7-8-9.... it will become a mess of balance issues and create one size fits all classes doing the game a great diservice.
