Oh yeah, cause the very first thing to try here is torture. That sort of thing only hits the table if Dinah decides to place her own freedom of choice over literally every human being, at which point I`m not sure 'little girl' makes up for 'supports genocide, actively suicidal, believes her freedom supercedes the freedom of every other human.' Death, may I remind you, severely limits your options for self expression. 'innocent' certainly stops applying the moment she makes that decision, assuming it is informed.
Is this getting through yet ? If Dinah is allowed the freedom to waste her power and be vulnerable to opportunistics fucks like Coil, or even just pure life risk factors, that directly, negatively impacts the chances of any human at all seeing another day. Having to spend up to two decades in a golden cage might suck for Dinah but if that increases the chance for all of humanity to survive a guaranteed to come extinction level event by even 1% ? Dinah can suck it up.
But hey, let`s make it simple. See, I`ve got a magic device. When it activates there`s a chance everyone dies. I`ve also got this innocent human here, who is aware of the situation and may or may not cooperate with you. If you torture him, not a lot, just some light physical and emotional pain for a couple minutes the chance for everyone to die when the device activates goes down by, let`s say... 10%.
In one hour the device will activate. You cannot prevent it, nor can anyone else.
Do you torture the human ?
