The easiest thing to do would be to buy a few usb socket modules (like this – https://www.amazon.co.uk/YOUMILE-Connector-Adapter-2-54mm-Converter-Microusb/dp/B07TVHR9LF/ref=asc_df_B07TVHR9LF) and either wrap or solder (seriously, solder if you can, but simply wrapping bare wires through the holes if you absolutely must would still work) wires to the outer power and ground pins.

Now wrap or solder the ground wire to the spring of the first battery compartment, and the power/positive wire to the final terminal where the “head” of the last battery would connect.

Since AA batteries are 1.5V (nominal) and three of them in series gives you 4.5V, it’s 99.9% certain that it’ll work fine off a 5V supply. Now you’ve just converted your LED strips to work off any old phone charger.
