He doesn't deliberately strike the opponent and he doesn't use excessive force. Both are requirements for violent conduct under the law.
This is correct. And it’s the wording of the laws that is important.
There are 2 routes to a red card for violent conduct.
The first:
“Violent conduct is when a player uses or attempts to use
excessive force or brutality against an opponent when not challenging for the ball, or against a team-mate, team official, match official, spectator or any other person, regardless of whether contact is made.”
I’ve highlighted the necessary elements. We know that Oliver did not send Thiago off for excessive force or brutality because this was his announcement:

Oliver’s use of ‘force’ in this context is to try and establish that the force was more than negligible.
So we’re into the second route to a red card:
“In addition, a player who, when not challenging for the ball, deliberately strikes an opponent or any other person on the head or face with the hand or arm, is guilty of violent conduct unless the force used was negligible.”
This requires intent. Thiago is not the aggressor. He is not looking at his opponent. He is walking away. The first contact is with the chest and then the arm comes up and makes contact with the face. You cannot establish that there was an intent to strike the face of his opponent.
Once you’ve ruled out excessive force and brutality (which can be done by the actual announcement made by Oliver) and once you’ve ruled out intent, violent conduct is not established.
