Not that I know of... but even if they did it would only be an approximation of what they could gather were search volumes based off of trends. Whereas going through something like Adwords would give you the data straight from the source (more or less). There are also other tools out there to help with that data as well such as Wordtracker (like BeardoCo mentioned) and SEMrush which offers some organic keyword volumes along with the rest of its data.
