Nope, Agito was watching the fight and remarked that Sho's death was part of his preparations:
Just because Agito's plan worked in service of the narrative, doesn't mean that it makes sense internally. You've got a potential ally in Sho/Guyver I, who you have now aided and abetted in the death of, and gifted the control metal to your sworn enemies. If the plan was just for Sho to infiltrate Chronos Japan, I'm sure there were less riskier gambits than this.
