Seems like it’s up to the pool guy to correct problem. The average handyman probably doesn’t have a fish tape over 100 feet.
Another option is a 1/8 rope tied to a rag or plastic bag and use wet dry vacuum to suck rope and plug through conduit. My last unground pool had a riser with junction box jus outside pool cage making it about a 20ft run
