The new one's are pretty cheap and let you put all your properties into separate liability compartments which really supplement the insurance a lot more cost effectively than having a bunch of separate LLC's. https://www.biggerpockets.com/blog/the-traditional-llc-vs-the-series-llc-which-is-better-for-real-estate-investors/

I also intend to act as an agent but only for a handful of deals a year to supplement the rental income to purchase more properties.So before I invest the time and money, I wanted to see if there are brokers out there that would support this approach? 

I know AirGMS, Guesty, etc. does this (even for free for small accounts), however if you are like me and use a 3rd party booking provider like Evolve, you do not have access to your listings for those tools to use so this is a nice supplement for better guest experience if you are in that situation.

My goal is to acquire 10 units over the next 5 years to supplement my income.  

Why not do neither and just supplement from the savings if you need it?

I will reinvest in CA down the road most likely for the appreciation play but for now I’m trying to capitalize on the cheap money and get some rentals that I can pay off in 15 years to supplement an early retirement. 

Having a professional license will definitely help you in the long run and supplement the earnings you make in flipping houses.

This can be a pretty fantastic supplement to your own investing.

On the other hand for you, it might be very beneficial so you can understand the markets and how this business works, while supplementing your income with your commission checks.
