Legal Question in Civil Rights Law in Louisiana

No. Only expert witnesses can be paid and they have to be qualified as an expert and their pay has to be disclosed to the other side. You can see how allowing witnesses to be paid to testify would lead immediately to people lying on the stand. Any attorney who offers a witness money could (and should) be disbarred. It is highly unethical and immoral.

That being said, there is an allowance in Louisiana law for a small fee ($40, I think) being paid to witnesses in order to reimburse them for expenses of travelling to court or a deposition. It is rarely used, but witnesses do have the right in certain cases to demand it when they are subpoenaed to testify at trial or deposition. That's it, though.
