I made an LLC in Maryland and I didn't get an EIN. I used my SSN to open a business checking account.

Would it be worth going back and getting an EIN? Would I be able to change the bank account? What would the benefits of doing that be?

In general, the taxpayer ID used to open the account is the taxpayer that owns the account. I am the treasurer of a small non-profit, and the non-profit's EIN is listed on our checking account. Having my SSN on there--except as identification that I'm authorized to perform transactions on the account--would have made me an owner, which is not what we wanted. Check with your bank to be certain, but I would change the account's EIN to your LLC's.
