True iff stage is an LLM-background stage — one built by llmStage that
carries the resolved LLM config and is therefore driven by launchStage /
completeStage. False for deterministic and sub-pipeline stages (drive those
with executeStage). Mirrors exactly the check launchStage/completeStage
apply internally, so a consumer driving a pipeline out-of-process can route a
stage to the right driver without catching a thrown PipelineConfigurationError.
