A catalogue of errors against at the Stadium of Light saw Sunderland gift Villa a 4-0 victory on Saturday - with all four of the visitors' goals coming before the break.
"It's a shocker of a performance in the first half after a good start," Larsson told the Sunderland Echo. "All of us 11 players out there have to take the blame.
"The goals we conceded in that first half were so avoidable, every single one.
"It's just a ridiculous amount of mistakes from all of us out there. Look at all four goals and none of them should be going in.
"That's the very, very frustrating thing.
"It's just embarrassing. For one bad goal to go in and for us to collapse the way we did, is absolutely shocking."
