I get that you believe that's what's happening, but I can't imagine any US court agreeing with you.
The law (and the US constitution) does not guarantee any particular platform for your speech. It just guarantees that you can speak, and courts have interpreted that to mean that you need to have some reasonable platform, and that laws can't put an unreasonable burden on your ability to speak on some platform.
As an aside:
> Telling internet providers what servers they’re allowed to let my device access?
The law does not target internet providers at all. They are not required to block traffic to *.tiktok.com or any of their IP addresses.
