Can property manager be held responsible for slip and fall?

[Roee Agami]

Hi,

Got a letter from an attorney saying a Door Dash delivery person slipped and fell and injured himself severely on my property (RI).

My property manager is responsible for clearing the snow off the property. Can they be held responsible for that?
Isn't Door Dash providing insurance for workers, or am I responsible anyway since thee was allegedly neglect?

I forwarded the letter to my insurance company, I don't have an LLC, just an umbrella.

Thanks!
