Is this accurate? Like, I know what you're meaning, but I'm pretty sure it's not ICANN doing it, and more so your domain registrar handing it over to the US government.

I think the most control that ICANN has over it is they could theoretically, if they wanted to, delete an entire top level domain. Since they do control the DNS root, but that is the most that they control from what I understand.

I don't know if they have the ability to delete or transfer control over an individual domain on legal request. I think that's outside of what their actual system allows for.
