If you don’t mind the runtime overhead OpenTelemetry would do the job (with maybe some sort of manual instrumentation for things like timers) and builds a service map.
IMO however if your services are closely tied together then how about grouping them together into one or multiple mono-repositories ? Or at least start designing your bounded contexts so that documenting by hand doesn’t become a maintenance burden.
