A loose pass from Maguire allowed Dortmund through on goal, before the goalkeeper made a save.
He then ran straight towards the England defender and screamed at him over the error.
It was a tough night for Maguire as he was also booed by the crowd in Las Vegas when his name was read out.
Earlier, there was another tense exchange between goalkeeper Tom Heaton and Brandon Williams over responsibility for Dortmund's second goal.

Scott McTominay was also given the armband for the game, with the defender recently axed as captain by manager Erik ten Hag.
Man United ended up stumbling to another defeat - their third successive one - in America as they now head home from their pre-season tour.
Diogo Dalot had put the Red Devils 1-0 up, before two goals in just two minutes from Donyall Malen overturned the scoreline.
Antony drew United level before Youssoufa Moukoko eventually gave Dortmund the 3-2 win after cutting out an Aaron Wan-Bissaka pass.

"Yeah, [the game was] two parts, the first hour was good, playing as a team, lot of dynamic, good pressing," a frustrated Ten Hag said. "So it was really enjoyable to see and that's what I wanted to say at half-time, but all of a sudden, they give two goals away.

"They were giveaways and that was annoying. But the last half an hour, it was bad, a poor performance. They didn't follow the rules at all, not in pressing, not in building up or when attacking. They were 11 individuals on the pitch.
"That wasn't good at all. I said to the team, I think it was a good tour, but you want to finish with a good performance and there was only 60 minutes that I was pleased with, but not with the goals we conceded because the first one was poor defending and the second one was poor in build-up.
"That's not us, we have to keep control, keep responsibility on the ball and it was the same for the 3-2. That can't happen and it's unforgivable, even if it's a friendly."
