Please help to confirm V+(min) 1.8V tolerance.
Our 1.8V have some tolerance, concern may not meet TLV9002 V+ range.

The supply voltage recommended operating condition for TLV9002 is between 1.8V to 5.5V. If your tolerance makes you go beyond this operating condition, the device may show some abnormal behavior. But, since you're within the absolute max rating, you won't damage your device.
-1.5% of 1.8V is just -27mV for a Vs of 1.773V
The device is tested and characterized at 1.8V and the device is typically functional well below 1.8V
I consider the added risk you must assume for using 1.773V (absolute minimum) as negligible.
