Amazon is obviously trying to pressure the Trump admin into easing the tariffs. Why wouldn't they? Why shouldn't they? Amazon is as much a political actor as any other company, and they have a major stakeholder when it comes to tariff policy.
Mainly with the concept of letting a ginormous multinational megacorp with more money and resources than 99.9% of the rest of America combined influence our political process is literally how we got here.
The CEO of Amazon is welcome to lobby as himself but letting an extremely already privileged legal fiction (an LLC) have more power over our society is just dumb.
