I think OP stated a lots of true thing but the conclusion is bit akward imo (where is the flaw in Allin luck !)
Random occurs in several place in poker, judging if you where lucky or not
on each decision can be made by looking at how much you won (or loose) compared to the EV of you play.
To determine correctly your EV you pretty much have to know what cards can be dealt after (and EV allin luck can wipe this random out when your decision was Allin), wich is the easy part. But you also have to know your opponent's range (the hard part).
In fact it's just a way to modelizate random in your EV calculation. You can apply this to many more thing than card dealt after your decision (slansky bucks), or range of your opponents (galfond bucks) : say you are playing against an unknown : you will assign him a range. If you latter find out that this guy was a true maniac and your range assumption was wrong (he shows you 32o where do you think it was not possible), it dont means you take a bad decision, it was just a good decision wich work
on average.
So no EV allin dont factor
every randomness in poker, but it still factor a part. And in sng where a lots of Allin occurs it's a good part imo. Therefore your asjusted ROI will still be
in average closer to the real ROI. But sure your true ROI can be lower with a negative Allin Luck , like your are super unlucky in your Allin but super lucky in your range.

I'm going to take an exemple:
You are on the bubble and pushing ATC from SB into the BB which is ridicously tight on the bubble. Your move is really $EV+, and this situation occurs a lot in low stakes SnG for exemple. But All-in EV luck will only take into account the hand when you are called, and BB will call you w/ a HR that crushes yours. So All-in EV luck program will say that you should lose a lot of money in that spot, and this is going to lower your All-in EV ROI, but not your theorical ROI.
The profitability of your shove with ATC for example rely on the fact that you have a 35% equity vs a 15% range (says its the calling range of your opponent). So if you win on a big sample size just 20% of this ATC shove you are unlucky. You win 45% you are lucky. Je sais pas si j'ai été clair
