Helpful script to prevent bots from running everywhere when testing squad disconnects:

sv_neo_preround_freeze_time 2; mp_chattime 2;
sv_neo_bot_cmdr_enable 1;
sv_neo_bot_cmdr_debug_pause_uncommanded 1;
neo_ctg_round_timelimit 99;

To test bots notifying that they are joining another player's squad, one can use bot_mimic 1 to have bots press the use key on another bot.
