I find this conflating of the US as a country and the US Government annoying. Megan Smith is the CTO of the US Federal Government, which is an entity separate from the US as a country.

It doesn't make sense for a country to have a "CTO". Do all technology decisions made anywhere in the US have to have her approval?

Logically, if she were the CTO of the US, she would have as direct reports all the CTOs of all the companies in the US.

The President is "of the United States" not "of the US Government", it doesn't mean everyone in the country reports to him - I think you might be over-thinking the terminology a little bit.
