Actually I'm not entirely sure she should get a big payout.
This is in America not the UK. Big payouts to individuals are what change the rules in the US. There's no obvious equivalent of our judicial review.

Big payouts to lots of individuals are even more effective.
But why blame the doctors here - if they hadn't allowed her to or refused her surgery it's highly likely that she just would've gone on to the next person until she found someone who would, because people of that ilk will just keep going until they get what they want.
As a pp says - blame the first doctor who says "yes".
i at least understand the the hypothetical arguments in favour of castrating boys who want to transition in relatively early puberty - doing so will to some extent stop them fully developing certain male characteristics in terms of facial bone structure, their voice breaking, and so on, stuff that's difficult to fix surgically 'further down the line'.
At the expense of putting their lives at risk if they later want a neovagina. Because one of the male characetristics they wont develop fully is a fullsized penis, so they don't have enough tissue from it to construct a neovagina, so it has to be done in an even more dangerous way.
One of the original Dutch protocol youngsters died as a result. The Dutch didn't fret about physical outcomes, the dead patient couldn't report on their satisfaction afterwards so was excluded from the figures. No-one pointed out "that's a 1 in 70 death rate for this treatment" until Michael Biggs got on the case.
