Than that TA at LIT might either need to get better training, or being replaced by someone who knows how to do it's job.
If you can't flip the Burgers correctly at McDonalds, they won't make them bigger either to help you with your task.
For someone NOT working in the airline industry, TIMATIC might indeed not be always clear.
But for a checkin agent, even at a remote outstation, I expect them to be able to understand TIMATIC and what it says.
If not, then either the training was not sufficient, or the staff just doesn't match the job. Either way, thats not China's problem. And hopefully China will soon make sure every airline understands this very clearly.
