There isn't a check box on the LLC form that says all your actions from now on must be evil. There are going to be citizen interest groups you disagree with and corporations you agree with. And a lot of high-profile lobbying is corporations arguing against each other.
If there was a simple heuristic like whatever corporations want is bad and whatever individuals want is good, then governing wouldn't be hard. Policy would be easy and not full of complex dilemmas with multiple competing interest groups that all have roughly prima facie coherent perspectives and interests.
Some of these groups will of course be wrong on further examination, but sorting that out isn't some one line test.
