VAR and Walton have it spot on, it's quite simple(ish) if you know the laws of the game you watch.
Benzema is in an offside position when the ball is touched by the Madrid player who goes in for the tackle with the 2 liverpool players. The ball then hits 1 defender and bounces off and hits another defender before going to Benzema. Those 2 hits, deflections or whatever you want to call them do not count as a deliberate play.
The issue is how to define "deliberately played".
IFAB define "deliberate" as :
Deliberate
An action which the player intended/meant to make; it is not a ‘reflex’ or unintended reaction.
Pretty sure anyone who's ever played the game would say that neither liverpool player deliberately intended for the ball to be played in the way it was. Sure, they deliberately went in for a tackle/block with the intention to get the ball but that's not how IFAB view these sort of things, a block, a deflection isn't a deliberate play.
