Why do you think the rest of the warriors would agree to the sterilisation plan? You know THEY'RE eldians as well right? Also they weren't interested in betraying Marley at that point (they probably still aren't), which is essentially what they would be doing by robbing them of their titans.

Also I don't think all the warriors combined stand a chance against the founding titan anyway. Not only can it take a form more massive than even the colossus and wall titans, but with one scream it could turn any nearby eldians into wall titans capable of easily crushing the warriors underfoot. Reiner couldn't even deal with a normal sized pure titan of Falco 1v1 when Zeke used his weak imitation of the founder's abilities to turn him into a small titan under his control.

Not to mention that the founder is also capable of manipulating their memories and bodies at will. Eren undid all the hardening on their bodies, so there's no reason that he couldn't simply do the opposite and force them all to harden into statues. Or even a crystal prison like what happened to Annie and the previous Warhammer Titan.
