Yes, all three keywords—"STOP," "LOOK" and "LISTEN"—will indeed produce the same response when configured as example opt-out keywords during the configuration.
However, depending on the provider, AJO provides a capability to set up custom inbound keywords that can be used to elicit different responses. For instance, if you were to define "LOOK" and "LISTEN" as distinct inbound keywords, you could then setup a journey to associate each of these keywords with a unique message.
The primary consideration when implementing such custom keywords and journeys is the timing of the message trigger.
