The issue is resolved thanks to Daeroth's post and by association Bad_Captain.
Repeating what he suggested at the end of the thread, installing the missing patches in this list resolved. The bots now buff and cast during fights.
1723_required_sql_corruption - Added this one manually because one of the entries already existed.
1736_optional_sql_feral_swipe
1737_required_sql_rule_and_aa_update
1753_required_sql_healing_adept_aa
1754_required_sql_healing_adept_aa_fix
1755_required_sql_fear_resist_aas
1786_required_update_to_aas
1790_required_aa_required_level_cost
1793_resist_adjust <-- This is probably the root cause (thanks bad_captain)
1803_required_tasks_xpreward_signed
1804_required_ae_melee_updates
1802_required_doppelganger - Change IDs to 682, 683, 684 and then run. You have to do this or it won't run successfully, and if you do, you can ignore 1813_required_doppleganger_npcid_change.
