I have a land use raster and several points on the map with population data (# of birds, # of chicks, etc.). I'm looking for a tool that's able to see if there's a correlation between the land use that point falls on and the values of that point.

You can't "correlate" nominal data with interval/ratio data, but you can do tests of "association" like

chi-square (google "tests of association for categorical data"

Extract Values to Points (Spatial Analyst)—ArcGIS Pro | Documentation

will get the raster values into your point file then you can do the correlation with the extracted values

using a number of options

TableToNumPyArray—ArcGIS Pro | Documentation  example in there

or more simply

Bar chart—ArcGIS Pro | Documentation

and other options (like exporting the table to Excel and doing it there or
