And an immediate transfer into a new LLC may not protect you since you still will own the seller LLC.I know investors do this kind of thing to save on property taxes.

Navigating personal issues between tenants can indeed be challenging, especially with the strong tenant protections we have here in Oregon.I completely agree with Nathan Gesner's advice.

In general, what kind of things should landlord be looking for when buying landlord insurance to protect our interest. 

what I like about MLS is you can go through a normal buying process. .wholesalers want to hype their deals info is wildly incorrect.. they want up front NON refundable deposits and your not getting any of that back.. they just try to create a false sense of urgency.MLS you take your time make your offers you can offer less you protect your EM you have inspections you can re trade within your contract time lines etc etc..MUCH more buyer protection that way.. the market will dictate the final outcome.. not a wholesaler hype machine and no real due diligence.

Aren’t IRA and employer 401k already protected from creditors?

Unlikely no need to change property management, they too are motivated to protect your home and have it rent ready. 

They are now offering a damage protection plan  and  cancellation insurance with an additional optional fee cost to the guest.

A well written management contract should clearly spell out what is expected of both the PMC and the owner, to PROTECT both and avoid misunderstandings.

Then an asset protection strategy might be required.

What protection can home owners have against this?
