Llorente at Ajax was a pretty good performance. Your general point is correct thoughEarly days but I struggle to recall many performances from Llorente, Janssen or Soldado that were as well rounded as Vinicius was tonight, even against easier opposition (not that LASK were a walkover).
If he keeps this up then he certainly looks much better value than plenty of other players in that price range (Joelinton, Haller, etc).
