From there, I would like to consider a 1031 exchange in the future to acquire more units.My current property management company suggested that they could handle a mid sized apartment building but I would absolutely not consider them for it as I believe they have overextended themselves and communication is lacking.

Through my studies, I met my current employer, who owns a construction company where I serve as the Sales Director.

Larger company -- tried to escalate to the owner. 

We have an insurance policy on the rental house (through State Farm), that includes a personal liability section, which is essentially equal to our current net worth.Given that a tenant could sue for more than this if an accident occurred, we are thinking about adding either LLC or an umbrella policy (or both) as extra protection.Any advice on which way to go, and if LLC, any recommendations for a law firm or company the Indianapolis area?

For full protection, your mortgage company will likely still require you to carry a landlord or dwelling policy.

I am also looking at a new company called Noshable that does grocery delivery precheck in and gives kickbacks as well.

Just tell them you work for the Property management company in my opinion. 

Quote from @Jonathan Bombaci: This year, our management company, which oversees 700+ units in Massachusetts and New Hampshire, spent over $209,000 on attorney fees, primarily related to evictions.

Also, make sure you have a great property management company who can be your "boots on the ground".
