If it is designed to take a load it is going to be heavier than a road race bike.
Definitely agree with go for steel.
You might look for all day, randonneuring, endurance, or even cyclocross bikes.
A bit of money but the Salsa Colossal TI is just over 20 lbs.
I ride a titanium cyclocross as my cyclocross, commuter, and long road rides (trade out tires).
It rides a lot like my touring bike but just lighter.
When you first posted the question you did not have a price constraints.
You might find a new 10 - 11 kg steel bike for £1000 but probably will probably sacrifice components.
You are going to need to up the weight or budget.
The steel version of the Colossal is under 11 kg and closer to that budget.
Look for a good used bike - I got my used titanium cyclcocross in great shape for close to that price range.
As for racks once or twice a year is not the same as never.
If it need to take a rack you need to look for a bike that does.
Calling a bike something other than a touring bike is not going to make it cheaper or lighter. I would not eliminate touring bikes from you selection. Just go for the lightest bike that does what you want it to do in your budget.
In that budget you are probably not going to shed 3 KG. If your current bike is ideal for everything you do then consider keep on riding that bike until you have a bigger budget.
