SONATA knew that she had gone overboard.
But she had to act as obnoxious as possible in order to make the culprit come out, and she could do that by making them angry.

Sonata noticed a tinge of dark energy from the head maid.
However, that level of dark energy could just be a "smudge." That meant Amelia may have been close enough to the culprit for the dark energy to cling to her.
But it was also possible that Amelia was just good at hiding her malice.
