Josh, it might be that you installed the google applications as a user, not for the whole system. So instead of:

sudo /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/install.py –uninstall

type:

~/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/install.py –uninstall

the ~ get’s expanded to your home directory.
