Firslty yes, seen too many issues with SORBS, we removed them about 3
weeks ago, the problems have been ongoing for months.
Secondly, like most DNSBL's they probably use rbldnsd, this does not
support TCP, only UDP

Why are you instead not doing a dig against these ips? It's clear
you understand that ICMP may be blocked, so why not use a check
method that actually uses the protocol you'd use to query them?
(send only to Dan accidentally, resend to ML)
I did it manually previous, without results collected, i tried to
tcptraceroute too (expecting that they responds to TCP requests),
etc. I used ping output to demonstrate the problem.
I do not know what dig's return code 9 means:

While i didn't compare it side by side with ping, it +- corresponds
with
ping results, at least in mean, that some responds and some not.
Here is one example of result with code 9:
; <<>> DiG 9.11.5-P4-5.1+deb10u6-Debian <<>> @113.52.8.11
163.44.213.129.safe.dnsbl.sorbs.net ; (1 server found) ;; global
options: +cmd ;; connection timed out; no servers could be reached
