In Single I/O mode, all eSPI signals are unidirectional, and you can use standard logic buffers (push/pull or open-drain, depending on the signal).

In other I/O modes, there are bidirectional signals, which cannot be handled on the electrical level without understanding the eSPI protocol. TI does not make such devices.
