Sotskova is too tall. If your favorite is same built as her, I doubt they could fully rotate a triple. What is the common UR problem when only Karen Chen has that issue?
There are many good examples who have proper Lutz technique. Nancy Kerringan, Bauil, even Tonya Harding (her misery was on her bad attitude, not her technique).
I agree...
It's difficult to get a good 3Lz period, but there is no case that classic technique means prerotation .
Quite the opposite actually. A clean spiky lutz with a good vault looks like nothing else.
Precisely because it is at the moment of picking and vaulting that the skater changes the direction of the arc of movement.
In my view, something beautiful is lost when a skater makes any kind of significant rotation in the new direction before leaving the ice.
Donald Jackson who landed the first ratified 3Lz to take the 1962 world championship had an amazing 3Lz.
See his jump pass starting 31 seconds in

But Jackson acknowledges that with the training methods of the time, it was difficult to get it down from a "quarter turn cheat" .
Yes, let's put it out there 'prerotation' was for a very long time referred to as a 'cheat'.
I don't think it's respectful of women to let a lower standard go by in the belief that it's the only way they'll get triples. Especially as they are not limited by the training approaches of the 1960s.
My preference would be for the rules to formalize the 90 degree limit as the have for URs on landings.
And then we will see these lovely, striking 3Lz again.
