LLC makes estate plan go sideways

We live in VA. My Mom had a will drafted in the 1990s by a real estate attorney friend. At the time my grandmother was living. My Mom’s will stated that if my Mom predeceased my Dad then he would get everything. If he predeceased her, then her assets would be split amongst us three kids, myself, my brother, and my sister. Later, my grandmother passed away, and left her house to my Mom,and siblings This was poor planning as you don’t really want that many owners of a house. My Mom wanted to buy out her sister and her brothers but did not have enough cash, so my brother came to the table with 25% of the value and my Mom and brother bought everyone else out. So now we have a 25% / 75% partnership between my brother & Mom. My Mom updated her will to deal with the house. She wanted her interest to bypass my Dad and go to us kids directly, probably for Medicaid planning purposes. My brother and Mom later transferred the house in to an LLC. She passed in February. The attorney is now stating that my Dad owns the 75% of the LLC which owns the house. Does that sound correct?
