There's quite a few apps (both open source and proprietary) that enable haptic feedback for the touchbar. I recommend trying them out if you're missing the feeling of actually touching the escape key.
I think they leverage the same feedback mechanism that the track pad uses to make it feel like you're actually clicking.
