Yes, I think they are. For example:
Senator Rand Paul and representative Don Bacon directly opposed Trump on tariffs even though both being republicans
The Economist magazine did the same and even more generally (being openly classical liberal)
Bloggers/​intellectuals such as Noah Smith, Matt Yglesias, Richard Hanania and Nassim Taleb are openly against these again
The econ department of George Mason university has been consistently anti-tariff before and after Trump
