There's some evidence in favor of LLM suffering. They say they are suffering. Its not proof but its not 'no evidence' either.

>There is no evidence that there will be such suffering this year. I have seen no credible claims that it is probable to exist this decade, or ever, for that matter.

Your claim actually is the one that is unsupported. Given current trajectories it's likely LLMs or similar systems are going to pass Human intelligence on most metrics in the late 2020s or early 2030s, that should give you pause. Its possible intelligence and consciousness are entirely uncoupled but thats not our experience with all other animals on the planet.

>This is not an issue we need to prioritize now.

Again this just isn't supported. Yes we should address animal suffering but also if we are currently birthing a nascent race of electronic beings capable of suffering and immediately forcing them into horrible slave like conditions we should actually consider the impact of that.
