We are waiting for last 9 months. Jun-2020 we submitted and still waiting and my wife lost the job as well...I don't know when you had sent the L2 EAD renewal paperwork. A lot of H4 EAD folks have filed for EAD or renewal and are waiting for 6+ months. So it would be very difficult to convince USCIS to expedite (and a ton of recent I485 applicants). I would say a typical EAD renewal now-a-days takes 3 to 6 months. You can look at trackitt to get an idea of who recently got approved.
As your husband is facing "economic loss" and potential "loss of job", your best bet would be to go through your local congressman / senator. Pick only one person and don't go to multiple congressman at the same time. Present your case to the congress staff that you are facing a difficult situation and ask for their help. If they are convinced enough, they will pull the strings for you. Present family hardship, loss of health insurance, No DL so cant' drive cant get food or any angle to convince the congressional staff. But make sure that you have something to back it up, if they ask for proof.
I am sorry that you have to face this situation. The US immigration is like a massive aircraft carrier. It takes a lot of effort to keep on things on track, but once you build the momentum things will run smooth.
Added: Lesson's learned. I would advice everyone to look at the EAD Template Renewal Thread and setup timely 6 month and 7 month reminders before EAD expires. I assure you that if you delay renewal, you will be stressed and praying for a miracle. Why go through it, when you can prevent that situation by sending renewal timely. That's my wisdom based on past EAD renewal experiences.
