Ask a Lawyer and Get Answers to Your Legal Questions
The authorities are correct - this is a civil matter.
You say that you tried legal services for seniors, but there may be other services that can assist you - try contacting your local bar association and ask for local referrals (they can give you specific names, but I would be looking for "Legal Aid" or "Housing Law Clinic" or something similar - you have an unlawful detainer/eviction matter that you are dealing with and that is what those types of clinics cater to specifically).
If you cannot get assistance, you can represent yourselves. Here is a link to Colorado Court's Self Help - https://www.courts.state.co.us/Forms/Forms_List.cfm?Form_Type_ID=28 It gives you information as well as court forms that you can use to answer the eviction.
I would recommend focusing on the eviction first.
In a separate action you can determine whether or not you wish to sue for damages for other things, but focus on the unlawful detainer/eviction matter first (These are two separate legal proceedings, and you must treat them as such).
