Does your site natively inherit permissions for all the list and libraries?
I would expect your statement to be true if your library is not inheriting permissions from the site itself. Otherwise, "Design" at the site level should be enough. The user would still need access to the list or library to see the workflows actions available there.
Here is the minimum permissions list needed for O365 https://help.nintex.com/en-US/o365/#o365/O365WorkFlow/Admin/Minimumpermissionsworkflow.htm
