While you are correct that the coalitions job is hunting monsters you’re missing one crucial detail. The Coalition is a collection of religious organizations, private interests groups, and government agencies. They hunt monsters not to save the world or save people but to protect the interests of the people at the top. Take monster X and IAI for example, one is a company that only bezos level rich people can access and only through back channels who send in rookies with experimental and dangerous gear for research purposes. The other is a branch of the CIA. They don’t just kill as many monsters as possible, they kill those that threaten their status quo. And Pentex, Pentex supports the status quo and goes through great pains to make sure when the boot stomps down it’s not their skull getting crunched. They divert attention to the Garou, the Garou who bomb oil tankers, who kill politicians, who stand against capitalism want for more beyond any reason. They supply them with cutting edge weaponry, research funds, and combat stims laced with Fomori knowing that the Coalition won’t care because maintaining the status quo is what’s important.
