The interesting thing about GMO crops.
At this point the primary reason for GMO is to make it immune to roundup and other pesticides/herbicides. So if it is organic but somehow cross pollinated then at least you don't risk the same contaminants.
From a chemistry use (like making VG) as long as your process doesn't make harmful impurities and your raw materials don't have impurities (like roundup) that may affect the chemistry process there should be no risk of additional contamination from the genetic material.
The question you always run into: Is the organic really organic? Am I getting the purity I am paying for? Is someone testing every batch or just rubber stamping the COA?
I've definitely seen it be bad, so in the end I fell for the source I trust to do their own testing and asked a lot of questions of the person I know who is in charge of the lab.
If you're doing the tests on the final product before resale you'll catch the kinds of impurities that would be a concern.
I still ask for the documents every time of course
