According to this page: http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Layer/Google/v3-js.html
"To use this layer, you must include the GMaps v3 API in your html." This means it will not help your count issue. You are still loading Google API even you use Open Street Map mostly. What you should do is make sure OpenLayers is doing "lazy" loading of Google API, i.e. loading Google API only (and only once) when any of the Google supplied map is viewed. You need to actually modify OpenLayer's core code to do on-demand loading. It takes extra work but should be doable. Google API provide a callback parameter in the API load you can use to invoke any function you intend to call before API load. If you need an example of "lazy" loading, check this: http://gmaps-utility-gis.googlecode.com/svn/trunk/agsjs/src/agsjs/layers/GoogleMapsLayer.js, pay attention to the _initGMaps function. As Rossko pointed out, key or no key both works, they all have counter.
