I slowed it down to half speed. There's a distinct whipcrack you hear with TK in TCW, and you hear it both when he hits Ventress and Dooku there. So yeah, seems like it. He probably also used TK when he blasted Obi-Wan and Anakin back.

Dooku wins easily. He’s a better duelist than maul. He’s a better duelist than anyone in the prequels aside from yoda, mace, sidious and anakin. In force power he’s only inferior to yoda, mace and palps. He decimated maul.
