you will never achieve "full anonymity" when using bitcoin because it is not designed that way. everything you do is increasing your privacy to the point that you can be almost certain that you are anonymous. if you want full anonymity then you must use physical cash with some additional steps!!

- Why do we need to run Bitcoin full node or EPS (Electrum Personal Server) to provide full anonymity. How is it any different from using Trezor with Tor browser, or using Trezor with Electrum running on Tor?

to hide your IP address. technically a third party can figure out which transactions belong to you when you create and broadcast a transaction even though there are methods to make it harder. so using TOR would hide your IP and makes it even more difficult to figure out who you are even if they could find which transaction came from you.
running your own full node compared to using another node through your Electrum client also removes the fact that you have to send all your addresses to that node and it can link them all together.

I am sorry. I still try to get my head around your explanation and please bear with me. If I don't use full node or EPS, my node will have to broadcast the transactions, so if i use my IP address (without VPN or TOR), my transactions will be leaked to ISP, right?

Lets assume, i use VPN / TOR and full node, the transactions will be broadcast using TOR address, but then how is it any different from not using full node and just use TOR and let a third party broadcast the transactions?. The third pary who broadcast the transactions won't be able to link my transactions to me because I am using VPN and TOR, and the IP address received on third party is coming from TOR.

- Which way is better? generating seed phrase using ian coleman offline then restore it on trezor to ensure Xpub is not leaked to ISP or any VPN, or to use Electrum offline with Trezor to generate seed phrase?

keys must be generated offline on an air-gap computer and never online. if it is online then you have more things to worry about than your privacy.

This is an interesting "if it is online then you have more things to worry about than your privacy.". Can you please elaborate on this more? . Are you saying generating seed phrase using Trezor or Ledger while i am online could lead to something worse than privacy? I am interested to hear your thoughts on this since you brought it up
