It won't happen, this is just fearmongering by people who are hellbent on fighting against an imaginary threat of a Christian Theocracy that much of the left believes is real.
The headline specifically says the Texas governor has signed this bill into law and there is a link provided for you to explore the text of that law which is detailed in the article. Child welfare service providers are now legally allowed to discriminate against LGBTQ youths and forcefully place them, along with other religious minorities, into Christian educational institutions. How many providers will choose to do that? Who knows. Probably not many, really. But, the fact remains, the Texas legislature and the governor have signed-off on this legislation that would legalize discrimination. There is no fearmongering about that. It is clearly outlined in the text, which anyone who is literate and possesses critical thinking skills could comprehend.
