I am sorry to learn of this situation.
Unfortunately, civil judgments do not have any particular priority (other than their date of entry) over other unsecured debts.
If the LLC had real property and you recorded your judgment with the County Recorder's Office, your lien would be given a priority date of that recording (so prior recordings would be senior and would be paid first, then if there was still excess from the sale of that particular property, your lien would be paid).
If the debtor LLC chose to pay other creditors before you, that is their right (there is nothing wrong with paying your debts).
If the debtor LLC went through a formal dissolution (doesn't usually happen it is far too expensive), then there is a legal process that is somewhat akin to bankruptcy where all of the debtor LLC's debts that were not already paid are pooled by class and distributions are made on a "pro rata" share.
If the debtor LLC had made fraudulent transfers of its assets (so made transfers of assets to its owners (members), or to family, friends, or anyone else, for less than fair market value, you would have a cause of action against both the LLC, the individual doing the transfer, and the party receiving the funds under the "Uniform Fraudulent Transfer Act" (but again, the payment of legitimate debts is not illegal and is not a fraudulent transfer).
