with "bayes_auto_learn 0" there is no reason to lock the bayes
database and the spamd-service should be happy with
"ReadOnlyDirectories=/var/lib"

the bayes databaase contains not only tokens, but also timestamps used
for
expiration. That's why you need to write to them

which expiration?

nobody expires or updates anything in a hand-maintained bayes

use_bayes 1
bayes_auto_expire 0
bayes_auto_learn 0

would this help?

use_learner 0

no, it leads in not use bayes at all

result: . -2 - ALL_TRUSTED scantime=0.1
result: . 0 - ALL_TRUSTED,BAYES_50 scantime=0.5

not only because the permissions, also because of wasted disk-IO

that leads in bayes not used at all
"use_learner 0" was the only difference to production

use_learner 0
use_bayes 1
use_bayes_rules 1
bayes_use_hapaxes 1
bayes_expiry_max_db_size 2500000
bayes_auto_expire 0
bayes_auto_learn 0
bayes_learn_during_report 0
bayes_learn_to_journal 1

not further tested if it also has an impact to sa-learn on the shell too - IMHO when "bayes_auto_expire", "bayes_auto_learn" and "bayes_learn_during_report" are all 0 there should be no locking
