I am having issues with: I run OSMC on a Raspberry pie 3b and use it to live stream media through the Kodi application. Currently, there is not a way to run PureVPN on this setup.

Your website tells me to use Librelect instead of OSMC. But, Librelect is out of date and no longer supported by its developers. The developers sit up and moved on to OpenElect. Which is more current. Neither of the latest versions of OSMC or OpenElect are supported by PureVPN.
