Wouldn't the middle ground be to have ISPs ban TikTok? The US doesn't need to create a firewall themselves, they can just rely on the fact that internet providers are in effect an oligopoly, and simply tell all 5 or so of them to prevent their users from accessing the website/service. This would, of course, be circumventable by a VPN, but that's a degree of rigor good enough for China, so it should be fine here.
