As to your specific theory, unless you're being sued by the state or a state actor, defamation suits are not generally considered to abridge the freedom of speech. Further, the question is not whether "certain personal liberties are at stake," it's whether the case is criminal or civil.

Every situation is different and no one should rely solely on information received from the internet. If you have any questions about your legal rights, you should consult with an attorney that practices in that area of law.

There is no right to appointed counsel in a civil case.
You might want to contact legal aid to see if you meet its criteria for the appointment of a lawyer to help you.
This is a summary based on incomplete facts. You should not rely on it as legal advise. No attorney-client relationship is intended to be formed.
