Isn't the $9B for all mobile advertising, not just mobile search advertising? According to a Glodman Sachs report for 2014, back then they estimated that iOS advertising accounted for 75% of Google's revenue on mobile. That would make the Android search ad space worth about $1B.

Do you have a link to that report? I'd be curious to see if that's just the US or worldwide.

It's not available online. The story originally came from the NY Times, but I think Business Insider has the best info as they directly quoted a section from it.
