Model has SRGB textures and no main texture. How do I combine?

Question

This model has liner SRGB textures and I'm really new to shader nodes and stuff and I'm really confused on how I'm supposed to get the texture to be the right colors with the output.

These are the images

And then I found that this is the base color somewhere:

{
      "ParameterInfo": {
        "Name": "BaseColor_0",
        "Association": "GlobalParameter",
        "Index": -1
      },
      "ParameterValue": {
        "R": 1.0,
        "G": 0.577581,
        "B": 0.38643,
        "A": 1.0,
        "Hex": "FFFFC8A7"
      },
