These two tables are what I could find in terms of the actual delay counters. It's my understanding that if you zero these out, the ECU then simply checks your current open loop fuel map cell against
Minimum Active Primary Open Loop Enrichment to figure out whether to transition to open loop or not. I'm basing this off of mad_sb's post here:
http://www.ft86club.com/forums/showthread.php?t=30418 His tables are different as he's using BRZEdit in that post though, so maybe we can't actually do this unless all of those same tables are defined in RomRaider and I'm just not seeing them.
On the subject of full-time closed loop though: What's to keep you from setting that minimum enrichment value to lower than the lowest value on your fuel map? That alone should prevent the transition to open loop completely, because that check is the last step in the process. If you were to then modify
CL Fueling Target Compensation A/B (Load) to mirror your open loop fueling, you should be left with a system that stays in closed loop and targets the right AFR all the time. Is there anything particularly unsafe about trying this? Or any gotchas in terms of fueling limits in closed loop defined elsewhere?
(This is just me thinking aloud basically, so please correct me if I'm wrong in any of my assumptions here.)

Closed Loop AFR A/B in RomRaider?
