I don't know anything about the BALLB, but basically you are a law applicant if you have a degree/diploma that allows you access to the examinations that will permit you to practice law in your home state. If your qualifications won't allow you to become a lawyer/solicitor/barrister, you should consider yourself a non-law applicant, even if your qualifications have a substantial law content.

Luckily for you, in the realm of human rights/humanitarian law, you usually don't need a qualifying law degree, but a degree with a substantial law content. In some programs you can even get an LLM with just a degree in the social sciences, so I am sure you will find something suitable to your interests.

If you are still unsure I'd advise contacting schools directly.

I agree with Poppett. Most LL.M. in human rights programmes in the UK don't require a law degree, though many applicants/students have them. Look at Essex and Nottingham. There are posts elsewhere here discussing LL.M. in human rights programmes in the UK.
