What determines Land Values

Well to a degree you can "create" land using human labour. If you have a wilderness, you can clear it, and you have virgin land. In a hip location, you can build a taller apartment.

Land is just another commodity within capitalism. Why would it have any special rules to it?

Because land doesn't behave like a commodity thus why LTV doesn't help you for land calculations. Parcels of lands can't be mass produced as they can't even be produced as they are function of nature where labor can only modify the land.
It would be more a commodity in a space economy where you can simply build artificial planets from raw materials thus could mass produce land yet that is beyond our current economic capability as you can't simply insert an extra acre of land to your property on Earth like could in space.

Supply and demand determine price, but price =/= value. Read Marx.

A bulk of Volume 3 is dedicated to Marx’s theory of differential and absolute rent. He spent a lot of time reading debates between Chemist and physiologist such as Liebnig and Haas to try and ground his theory in the materiality of production. Marx wrote the manuscript for Volume 3 in 1864-65, so it wasn’t towards the end of his life.

Would you mind talking about it at all? I'll gladly read volume 3, but I just want to know if there is a relatively simply overview of his ideas on it.

Because land technically can't be a commodity since no social labor went into it, and yet it has a price (and therefore, somewhere up the chain of the transformation process, a value). Marx was well aware of that issue, associated land value with rent and sought to address it in the third volume of Capital.
