Sure- I think a T should apologize when needed. My T has done in a number of times in the three years that we have worked together. The latest time he did was when he wasn't careful with his words and said something that really hurt me. So, I brought it up and he didn't realize he had said it in those words and said he should have been a bit more careful. They are humans- so T should apologize just as any of us screw and need to.
