Standard exterior plywood sheathing (on top of ext stud wall, underneath finish ext siding) has formaldyde, glues all of which are toxic. What can I use that will be non-toxic, or at least much less toxic?
Thank you very much!

OSB and plywood exterior sheathing no longer contain Urea Formaldehyde, so they really aren’t that toxic anymore, especially on the exterior of a home. But by all means source a non-toxic one if you like, but typically it doesn't have a measurable impact on interior air quality. There is an interior grade plywood called Purebond from Columbia Forest Products in case you will have any plywood on the interior. I called the company to check and they tell me that it isn’t structural unfortunately. So unfortunately we don’t have any leads for you.
