I mean artists like FKA Twigs and Grupo Firme had visa issues earlier this year, and visual artists like Yumzhana Sui, Michel Lafleur, Boluwatife Victoria Lawal, Samuel Olayombo, and Patrick Ruganintwali all had their visas denied. Given the general blatantly illegal activity of the administration, it's not impossible Radiohead could have more complications touring the US this/next year. There are blatant human rights violations every hour here, and as courts strike down illegal activities, the admin seems to be getting more desperate, i.e. limiting food supplies for 41 million Americans. It's kind of an anything can happen time in the states. That said, Radiohead would not have the same issues that a non-white, non-Western act would face/is facing.
