The red path is if you want to use Vicksburg (upper level roadway) to cell phone waiting lot - you can exit T7 from the upper level and use the parking garage to reach T1.
The blue path is you want to use Worldway (lower level roadway) to cell phone waiting lot - you can cut across the T7 parking lot to save time.
Either path will take about 10 minutes if you walk fast, 15 minutes if you walk slow. The lower level path is more direct but has more crossings. The upper level is longer but fewer crossings.
The two green X marks the spots that you can get dropped off and walk in to the terminals.
Note that neither are technically legal drop offs - one is located on private property (Hyatt driveway/parking lot) and the other is a bus stop. I've done both and never had a problem but your results may vary. I've also found that you can pull over anywhere on Vicksburg between 96th st and Century Blvd to get out of the car if you do it discretely... don't take a long time, just grab your bags and go. Your Uber driver may not like this idea because I believe this area is geofenced but never hurt to ask them because trust me,
it is faster to walk from Hyatt to T4 than sitting in the car during peak morning hours when all the Uber an Lyft cars are using the upper level.
Of course you can always drop off at the cell phone waiting lot as well and walk across the street to the LAX shuttle stop (green circle) and take the shuttle to the terminal.
