Shouldn't PITIA paid by LLCs be excluded from personal DTI calculation?

[Jim Collins]

I am paying mortgage for all the rentals from business accounts. The only PITIA paid from personal account is for a personal residence. I am trying to get a 5% down first home buyer conventional on a fourplex for my daughter to househack and lender I spoke with says that we need to calculate the debt for all the other properties I own and pay from businesses into DTI.

Is it true? Or am I speaking with a wrong lender? And of so, any lenders in Texas who can help me get this conventional mortgage? My personal residence payments are less than 15% from combined personal income. But if we add all the rentals sure DTI will be over 50%.
