Is it against adsense TOS if I preconnect origins like pagead2.googlesyndication.com, googleads.g.doubleclick.net, tpc.googlesyndication.com and others that are commonly used by adsense?

The implementation will be like this:

<link rel="preconnect" href="https://pagead2.googlesyndication.com/">
<link rel="preconnect" href="https://googleads.g.doubleclick.net/">
<link rel="preconnect" href="https://tpc.googlesyndication.com/">

Perfectly fine to do. web.dev, a Google project, recommends doing exactly that at https://web.dev/uses-rel-preconnect/.
