When you run that curl command, TikTok already knows your IP, which is a very valuable piece of information. Unless you maintain a server that has its own IP and does nothing except de-personalizing TikTok links, and always visit the tracking-free URL from another computer with a different IP, something like that. While it is possible, I am pretty sure most people, including most people here, don't want to do that.
Sounds like a new SaaS to remove TikTok tracking. Some way to redirect any TikTok link w/o the tracking. You could then do the most SV thing to offer it for free and store the same tracking info yourself and/or deliver ads from your accounts
On the other hand, I don't think most people consider a public IP address to be private or protected information. If you're interested in finding the "root" content URL, which lives on a TikTok domain, then you've already implicitly signaled that you accept them knowing your public IP address.
