Welcome to LQ!
There is the Arch netinstall. With it, you can choose whatever packages you want (requires internet connection). OSS is in the official repositories so you can choose to install it.
Arch, however, requires some work to install and customize. If you'd be willing to wait until after the initial install to get OSS, then you have more options. For example, Debian has some OSS packages.
