An extremely silly question, buut...

What you can do is have the universe with almost no minerals, but high amounts of orgs and rads.
Then only give the FT access to a resource converter. But keep the FT tech levels really low for offense, so they cannot attack anyone.
Everyone will need minerals to build, but they'll have to buy them from the FT by exchanging other stuff.
The FT can be attacked, but then they might not trade to you anymore. At which point you would need to go through a second party to get your minerals.

Plus, like the Gryphin suggests, to avoid whomever playing the FT from making a deal with one other player (and ruining the game), you put two FT's. Then you'll have some nice competion. On top of that, then you can make victory conditions for the FT's as they compete directly against one another.
