LL-HLS removed HTTP/2 Server Push from the spec back in January: https://mux.com/blog/low-latency-hls-part-2/

This was driven by poor server + client support at large, and the complexity it introduced. LL-HLS instead uses byte ranges and open-ended ranges over HTTP/2 - almost Comet-style - to handle CMAF chunks.
