An Android phone isn't what's referred to when people say "Linux phone". What they're referring to is a phone running GNU/Linux, typically running one of the GNU/Linux phone shells/desktop environments.
Android is Linux.
It runs Linux but it isn't a "Linux phone" in the sense used here.
My friend's daily driver is a PinePhone. So usable as a daily driver.
What you've said here doesn't contradict what I said. A phone running Lineage OS is explicitly not what people are referring to with the phrase "Linux phone".
I know
Apparently not.
projects like GraphneOS/LineageOS ... our best chance at getting "Linux phones".
To repeat myself: an Android phone (for example, running GrapheneOS or LineageOS) isn't a "Linux phone".
Edit: I don't want to buy a phone. ... Sorry for the bad wording.
I'd suggest editing the post's title as well.

To which project would you give your money to accellerate it?
I would reign in your hopes of accelerating a project using money, unless you have enough money to pay someone's salary for a significant period of time.
That said, I'd suggest postmarketOS or Mobian might be the most worthy of donations.
I would donate to whoever is making the best progress and having the most impact.
OP is asking who that is.
