Can you connect an expansion tank with a flexible line?

Would it work if I built a shelf next to the water heater, set an expansion tank on it so the water inlet is facing down, and connect it to the water heater by screwing a tee onto the inlet valve of it? The way it is set up now, flex lines connect to the tank for the water supply. Do they make a tee (is brass the best bet?) that is female on one end and male on the other two?

An expansion tank will work perfectly well with a flexible connection and will work perfectly well anywhere in the system with no valve or check valve between it and the water heater.

You will have to check the plumbing code for your city.

I have not seen tees with both male and female ends but you can get gender bender nipples.
