Last month I wrote a tool called "brr" - eBPF Runtime Reporter and Profiler. It displays a bpftop-like eBPF program summary, but you can also zoom into any program to see its source code lines (if available) and profile the eBPF program activity and any kernel code activity called/caused by the eBPF program for the full picture of where your eBPF program time/latency is spent.

I wrote it mostly with Codex for my own use, but just pushed the latest release to GitHub (with screenshots) in case anyone else is interested:
