Log data model will use TraceId,it should be the same

[dmathieu]

Do you mean why use TraceID instead of TraceId? If that's the case, using ID instead of Id is a Go idiom.
The specification is a means for all libraries to behave in a similar way. But each of them should also respect the idioms of their language, not blindly follow the spec.

@dmathieu is correct regarding the capitalization difference. If your question is also about why SpanContextConfig does not have struct tags that would cause it to be marshaled using TraceId, that struct is not intended for communication, only for use with the SDK. The propagation package should be used to propagate trace context information.
