This is expected as errors events need to be attached to a trace context, even if span recording is turned off. This is called "tracing without performance" and more information can be found here.

This is useful if other services need the trace id for continuing tracing like the client SDKs. Generating IDs should be a very light operation unless you are seeing it affecting the performance, is that what you are seeing here?
