Answer 2

Create your List Definition using a Web Scoped feature. Set the feature attributes to Hidden=True.

You can then activate your feature manually using PowerShell for that sub-site.

For further automation you can either staple your feature to specific templates (so it is automatically included in sites which uses a specific template) or reference it in the WebFeatures element in the Onet.xml of your custom site definition.
