Another good place to check is the US Interagency Elevation Inventory. https://coast.noaa.gov/inventory/
2016 South Central NE NW Kansas Lidar
2018 NRCS Kansas Statewide QL2 Lidar
In the USGS, I usually select the metada for the lidar file, find the lidar tiles in shapefile in the directory and then copy the download link. I then add a field to the lidar tiles and calculate a path using the full download directory path and the name field replacing for each path. Select and paste the path the into a download program like Free Download Manager or others to download in mass.
