You can take legal action but the likelihood of recovery is probably slim. Are the former tenants employed? Do they own any significant assets, boats, motorcycles, etc. Before paying an attorney for the lawsuit, sit down with the attorney to discuss the likelihood of recovering the money after you win the lawsuit. Quite often the lawsuit in this type of case results in a judgment that is never paid.
It does not sound like the judge did anything wrong. If you use a PO Box for the address in a Three Day Notice you have to provide an additional five day period for mailing the payment.

For personal injury claims most lawyers will provide a free consultation.
Consult an attorney as soon as possible to determine if you are entitled to reimbursement for the rental. Did you suffer any injuries? If so, you should be able to get a personal injury lawyer to handle your injury claim and the property damage/rental issue. Unfortunately, some personal injuries refuse to assist with the property damage aspect of the accident case but there are many others that will do both at no charge for the property damage/rental issue.
This sort of business planning is best pursued with the assistance of an attorney. The attorney needs to know the specifics of your situation and it is not a 'one size fits all' matter. Generally speaking, one can create a corporation or LLC and have different division within the entity but how that is structured depends on your needs.
