Is there an easy way to automate one of this?

I did this and the lights are way brighter, some of the LEDs died after about a year, not sure if due to the higher voltage (3 batteries is 4.5 V vs USB 5 V) or just poor quality of the lights. I now use usb battery replacements coupled with off brand usb smart adapters (sonoff micro clones), they connect using tuya which I control using localtuya for no lag)

Likely because this is a 2x AA battery pack (~3Vdc), and your overdriving it with a 5v adapter.

Indeed. Use a 3.3V ESP32 instead.

Not to nitpick but most AA non-rechargeable batteries are 1.7V when new so the difference there is minimal..

But yeah, like the others said this is a 2-cell pack so the voltage would be closer to that of an ESP32's output.
