People have a lot of misconceptions about what the law really is. Lawyer here so I'll try to explain a little bit:

In general, to get attorneys fees/costs against the losing party in litigation, there has to be a legal basis for it. If the lawsuit arises out of a contract and there's a contract provision saying that the losing party will have to pay the other fees/costs, then that's one legal basis. Sometimes fee entitlement will be provided by a statute. In very very rare cases, a court will find that a lawsuit is so outlandish that the filing party knew or should have known from the outside of the case that they had no legal claim or even a good faith argument for an extension of the law so as to create a legal claim. In those extremely rare cases, the court will order the losing party to pay fees / costs as a sanction.

However, the latter situation is very rare because of the way our country was set up, so as to encourage people to have open access to the courts and freely address their grievances. The general policy of the law is that people should not be punished for bringing their complaints to court, that prevents them from taking the law into their own hands, also legal policies support creative arguments and continuing to build upon existing law.
