I think it could very well be that your therapist really wants to let clients initiate things in the way they want to. Have you noticed the same pattern in session? Such as letting you lead the session with the topics and pace that you choose, for example? Maybe she clings too much to textbooks saying she should not initiate. I think that if you want to continue with this therapist it might be a good idea to express how you find this dismissive - that way you can explore how come you find it dismissive rather than something else and she can also see how this impacts you and perhaps change some things. I would feel unconfortable if I were in your position too, but personally, from what you told us here, I don't think she's being dismissive - she has actually heard you and changed soimething trying to adapt - she came up with the handshaking to help have a proper goodbye. Sure, this isn't something she does only with you, but in your case she suggested it to help with something I gather you expressed about your needs from her. That said, I also have the need for the other (therapists included) to initiate at least occasionally, so I'm sorry your therapist does not meet your nees. ut you could take this as an opportunity for growth, to explore how you feel and let her know.
