Hello

I just bought the game and the DLC. And I am downloading the offline installers.

The base game is 28 parts, and the DLC is 11 parts?

Im guessing I can skip all of the patches?

Yes, if you download the 28 files for the base game and the 11 files for the Phantom Liberty expansion (it's not really a DLC...), you can skip the patches.

Thanks for the answer, it is as I was hoping then.

What do you mean it is not a DLC? Phantom Liberty is even referred to as a DLC by GOG themselves?

That's because GoG are clueless of the meaning of abbreviations.
Yes, Phantom Liberty is a DLC in as much as it technically is DownLoadable Content, however the content itself is in this case an expansion.

DLCs are generally considered small things, like an added gun or vehicle or clothes.
