I saw a recent blog post about a partnership between Purism and PIA: https://puri.sm/posts/purism-becomes-pia-first-oem-partner/
... which suggests that the free code Librem Tunnel app (a branded OpenVPN client) will be a way to connect to a PIA-supplied VPN service, without using non-free software, or having to fuss around with manual config. So far, I can only find mobile versions of the Tunnel app and I haven't got it working with either of the Androids I have (4.4.2 and 4.4.4). It just crashes on both, as soon as it's opened.
