Only Fredo would be dumb enough to believe there was a viable plan to kidnap Michael. I think it is more telling when Fredo tells Johnny during that "wrong number" conversation that they'd got him in deep enough already.
And btw what would make Ola think Fredo was privy to whether or not Frankie was on the level with the Rosato deal?
