Headless server minimum players

[DagMagnuson]

Is there a way to run a LAN headless server that can be started with one human and one cpu player? Or all CPU players?

To my knowledge, that's not possible on a headless unless you edit the source code. The requirement to have at least two human players in a game was added to prevent users from starting games too early or to block servers for other potential players.

You can, however, run a "headful" server this way, and can even script it to a degree (see --help output on a command line).

Actually, you can set MinHeadlessPlayersRequired in the configuration.  This is an undocumented option, but you can find it in this file.
