Per review: --json still went through _create_host_backend_client and _call_host_backend_with_optional_tenant, both of which prompt interactively (writing to stdout, reading stdin) when the module- level _no_input flag is left at its default False. deploy_listeners_ list never set it, unlike the main deploy command, so a missing API key or an org-scoped key without LANGSMITH_TENANT_ID would corrupt the JSON output with warning text and could hang waiting for input that a scripted invocation never provides. Sets _no_input = json_output at the top of the command, same pattern _deploy_cmd already uses, so both paths raise a ClickException to stderr instead. Added a regression test that fails without the fix (click.prompt is genuinely invoked) and passes with it.
