Apparently the ALU BNGs are configured to not respond to traceroute and icmp. On most modern routing platforms such traffic needs to be handled on the CPU instead of being switched on line cards (like all other traffic), contending with other on-CPU tasks (e.g. BGP or similar, RADIUS traffic etc., monitoring traffic).
So, this is normal although it would be useful to see the responses from the BNGs to identify or rule out DSLAM backhaul congestion.
There is still some variance in latency on your traceroute, it may be more useful to test with mtr or winmtr or similar (e.g. Pingplotter on Windows, Traceping on Android, both of which I haven't really used) which gives a better indication of where latency is introduced if there is time-variant latency.
