I definitely would want the mail to go to the correct place.If someone wanted to sue you, the fact that you ignored changing your address would be a good argument that you are not maintaining corporate formalities, potentially having the protections of your LLC ignored.Most states have annual filing requirements for the LLCs so that would be a good time to update it.  

Consider if it will truly benefit your tax position, liability protection, or asset management, or if it will just add unnecessary paperwork.If you’re in a state like California, keep in mind that you’ll have to pay $800 annually to the Franchise Tax Board, file a periodic Statement of Information (SOI), and submit a Beneficial Ownership Information (BOI) report.It’s a good idea to consult a real estate attorney to ensure you’re making the best decision for your specific needs.
