Yes and no. A library might check for the status codes, but then what? Will it throw an exception? You'll have to catch them.

Will it fail silently? If so, is your code prepared for null to be returned instead of parsed JSON objects. You'll have to check for that.

Using a library isn't going to save you from handling all the error states and unexpected response bodies. It'll just change the documentation you're reading and the name of the abstractions you're dealing with (e.g. status codes -> exceptions)
