It's been like 5 seconds since I last heard someone here using Lauri's PER as proof as to why he's not worth a 15 million dollar contract.

PER is an outdated stat.
PIPM, RPM, Raptor are better overall. Lauri doesn't really stand out in those.
We'll see what he does this coming season.
PER is a box score stat, and it is somewhat outdated perhaps as a pure box score stat.
I agree that PER is not a perfect all in one encompassing stat (to which I don't think there is such a stat, though Raptor attempts to be), but it has a pretty obvious use to it that is still valid today. If you look at something like RAPTOR, RPM, or PIPM, they'll tell you that Shaq Harrison was a better player than Zach LaVine for the Bulls last year. In fact, Shaq Harrison, vet minimum guy that he is, is clearly the best player on the Bulls by Raptor last season.
There are extreme flaws in stats that apply value to an outcome based on correlation rather than causation which is one of the basic principles of statistical analysis. Every stat you named, at its core is a correlation based stat not a causation based stat which is why every stat you named has some really funky outcomes.
So I wouldn't say that PER is outdated or even worse than those stats, you should know what PER is good at and what it isn't good at as with all those other stats you mentioned. If you want causation based stats that look at what a player actually did, you should be looking at things like PER which I think is still one of the better ones. If you want to look at correlation based stats the ones you mentioned are all there.
What I think would be interesting, and maybe someone has done so but hasn't really made it popular, is if someone created an updated stat like PER but to take into account things like how often they are assisted on shots and other modern box score / causal type data that wasn't readily available when PER was introduced.
