The paintkit download is provided by Indiafoxtecho when you buy the Long-EZ via a third party store.
Not sure if it’s included with the MSFS marketplace version. The paintkit is only for the livery not for the interior tho.
Sure you can use the the cockpit for your liveries if you provide them as free download and include credits in the readme (and also include credits on the site where you release them)
