Could you clarify how "damage prevented from hits" works in the context of Juggernaut's Unbreakable node? I assume this refers to only prevention of damage taken, not prevention of life loss, but petrified blood does use the word "prevent" and the wording on the Unbreakable node makes it a little unclear as to how the two would interact.
Petrified blood does not prevent damage. It prevents loss of life from damage. preventing damage happens earlier than that.
