Thanks for everyones help. with a fresh set of eyes(in addition to your assistance) I was able to track down the issue. I am a wordpress/Magento dev so I was a bit puzzled by the eroneous scripts pointed out to me in this thread, so I started there.
In wordpress my colleague who built the page had a plugin called layerslider7 enabled. it did not seem to be used. This plugin was not only loading the following script, but the ancient version of TweenMax.
var oldGS=window.GreenSockGlobals,oldGSQueue=window._gsQueue,oldGSDefine=window._gsDefine;window._gsDefine=null;delete(window._gsDefine);var gwGS=window.GreenSockGlobals={};
I found this declaration in the middle of a bunch of LayerSLider7 scripts. I disabled the plugin and Boom! back in business.
