There's an issue #626 about this problem. I ran into it today too.
Currently, when getting signing keys, PyJWKClient assumes that a key is intended for signing, only if its "use" claim is set to "sig". This is not entirely correct, as this claim is optional. If it's omitted, then the key can be used both for signing and encryption.
I guess the correct way to process fetched keys is to check that their "use" claim is either "sig" or missing. In this case, we can safely append it to the list of signing keys.
