The way the US had dealt with issues like this is in the courts of law through an evidentiary process, not by political decree, which will get slammed down in the courts anyway.
Show that TikTok causes active harm compared to FB/Twitter, put that on the public record, and clear the obstacles for a bill to ban.
You're not wrong, but it's also true that China is exploiting our liberal, rule of law way of doing things in the USA.
As for a record of doing harm, mobile apps like douyin (China tiktok) have enabled a total police state in China. Say the wrong thing in a private conversation in an app, and the police will invite you to have tea.
Try being critical of China on tiktok and see how long it takes before you get banned. This isn't a hypothetical, it has already happened.

How would that work in the case of TikTok. If for example the US Department of Justice were to sue TikTok, what law or regulation would it allege TikTok to have violated?
>the US had dealt with issues like this
This suggests that there were law suits in the past. Who were the plaintiffs and the defendants? What law were the defendants alleged to be in violation of?

That's exactly what DOJ would be tasked to do, build the case against them. Surely if the risks are so dire, they can find something to persuade a judge.
