Is it okay to say local zones are an extension of edge locations as they both focus on bringing services closer to the end-user. With local zones allowing more services such ec2 instances and edge locations focusing on CDN and route53

Mainly edge location is used to host the web content (Statit or Dynamic) it may be in the form of Cache or the uploaded one by a user while local zone is mainly used for infrastructure deployment that places compute, storage, database, and other select AWS services close to large population. Means Edge locations might be small centers while local zone are bigger one so that it can provide the compute powers based on deployed infrastructure in this zone.

No. Edge Locations are used for Amazon Route 53, Amazon CloudFront and AWS Lambda@Edge. They are located in places outside of regions.

I think of Local Zones as Availability Zone that are outside of the Region's normal geographic description. Normally, all AZs belonging to a region are within a particular distance of each other. A Local Zone is outside of that distance, sort of 'attaching' itself to a more-distant region. It's a way that AWS can provide more geographic coverage without having to create yet another multi-AZ region (which is rather expensive!).
