應該是可以的吧，Google 的答案

Yes, you can run multiple businesses under one LLC. There are two ways to do this: 

 

• Run all business activities under the LLC name
• Register DBAs ("doing business as"), also known as Fictitious Names

Running multiple businesses under one LLC can offer operational flexibility and cost-saving advantages. However, each business activity should be accounted for separately, and it's essential to maintain clear records and compliance. 

 

The route you choose can impact you in several ways (including your liability and tax obligations), so it's critical to do your homework and weigh the pros and cons.
