So I installed this together with some other Mods, one of which is "Any Planet Start", however, in the selection box there are only the Vanilla Planets, not Lignumis. I tried reinstalling the Mods and multiple Restarts, but it didn't work. Do I have to add the Planet myself over at "Any Planet Start" or could there be a mod that is causing all of this?

You don't need Any planet start to start on Lignumis. It's the default to start there and the mod Lignumis does that on its own. Any planet start can be used to choose the second planet after Lignumis (the planet that Lignumis orbits). See the mod description.
