I picked up Fallout 4 on GOG for Fallout London but that does not mean I do not want to use Fallout 4 to play the other DLCs and access the Creation section.

Instead I can only play Fallout London which by the way popped up an error wanting F4SE which I cannot install since I do not have access to Mod section.

I just refunded the game.

I'm sorry, but what do you mean "do not have access to Mod section"?

Refunded a free London mod. lol

I think he meant refunded Fallout 4

And yeah, the installer should probably make it clearer there are ways to use Fallout London with a mod launcher. It's in the readme, but the default installer just updates your FO4 installation

Been using GOG for a long time. It's nice to have a high profile mod give such a lot of publicity too. It's a bit sad that the installation is such a weird and not entirely pleasant way to do it.
