COS RFE to B1B2 after After H1B layoff

After being laid off and switching to a B2 visa for job hunting, I initially applied for a six-month extension but was only granted four months. Now, four months have passed without securing a job, so I applied for another B2 extension. Last week, the extension request received an RFE (Request for Evidence). Has anyone recently encountered a similar situation? What are the chances of rejection after an RFE? Are there any other options available at this point? Does anyone have recommendations for a lawyer experienced in handling such cases? (I’m hesitant to take any more risks.)
