It's not one click if you have 100+ junk items - it's a hundred clicks.
Wich only gets us back to previously asked question ...
Why do you even have 100+ junk items in the first place. O_o
If an item can be used for crafting, it's automatically not junk - it's a crafting material.
So ... until game will be released, we dont even know if items we are talking about even are "junk" ?

What makes you believe they are?
Good question ...
Since i never stated they are, i would dare to either say nothing ... or ask you why do you think that.

But lets play for a second.

Its simple matter of deffinition.
Anything that dont have zero probability is possible ...
And all i said was that its possible.

How do you imagine these skills would be implemented?
No idea ... i never played any Divinity game, so i dont even know how they work.

Also, not quite my place to figure this out ... Larian have their own people who "would" working on that (if planned ofc), as part of their job.

I'm not fluent in the rules, so feel free to correct me, but I don't believe PHB has any spells, feats, or class features equivalent to either Lucky Charm or Telekinesis, excepting the level 5 spell with the same name.

Description of those feats would be helpfull tho.

Another thing. I have no games development experience, so again correct me if I'm wrong, but it seems to me that if Larian planned to graft some systems from DOS onto BG3 wholesale, they'd have done so in the beginning.
Well, im not so sure to be honest ...
It would make sence if they would want to make this game to look as much DOS as possible ... wich they clearly didnt (and kinda failed in eyes of some people as it seems) ...
So its also entirely possible that they decided to keep only the most essential things present, and leave everything else for "futher development" to be added once it will be adjusted to not look so much DOS-like.
