My interpretation was she is not herself disabled, works with a rescue, and has a great dog she's trying to place. I think she wanted to find out how to get him into service work. I haven't seen her around lately so I'm not sure if she'll respond herself, which is why I'm giving my lame interpretation.

Yes, therapy dogs are not service dogs. We mention them on the main site in order to clarify the difference but that's the extent of it. A therapy dog is trained, tested, registered and insured so that it may be taken to hospitals, nursing homes, and other facilities to visit people and cheer them up or educate them (such as a reading program). A person with a therapy dog might coincidentally be disabled, but that is not related to the dog being a therapy dog and most therapy dog partners are not disabled. Therefore, a person with a therapy dog has no more rights to public access than any other pet owner. In fact, they must have permission before visiting a facility that doesn't ordinarily allow pets. The whole idea of getting them tested/registered/insured is to assure facilities that the dogs are suited for this sort of program so they'll agree.
An ESA (emotional support animal) is a pet belonging to a person with a disability and some sort of concurrent mental illness (such as depression), or maybe their disability is due to mental illness and the ESA is part of the treating physician's treatment plan for them. Those are the two elements: 1. owner is disabled, 2. doctor recommends presence of pet for therapeutic purposes.
ESAs are addressed in two areas of federal law, the FHAA (housing, including "no pets" housing) and the ACAA (flying on commercial aircraft). In any other situation, an ESA is no different from a pet, and the owner has no additional rights beyond those of other pet owners. In short, unless state laws grant them public access rights, then they can't take an ESA out shopping or whatever. We do include discussion areas for ESAs because our focus areas are: disabilities and service dogs. A person with a disability and an ESA should fit in just fine and would hopefully benefit from the community experience. We do have members here, long time members, who do not have a service animal. And that's just fine. They're still part of the family. We have members who are not disabled, but know or care about someone who is. We have puppy raisers and trainers.
A PSD (psychiatric service dog) is one that receives the advanced training of a service dog, but specializes in doing things for a person with a mental disability that they cannot do for themselves. Just like any other kind of service dog. We have a large population of PSD members here, especially if you lump all brain dogs together (TBI, seizure, developmental, psychiatric, autism, etc.).
It's not that people with therapy dogs are unwelcome, it's just that that experience is fundamentally different from the disability/SD experience. Therapy dogs receive around 8 weeks of training, compared to 18-24 months for a service dog. Therapy dogs have no legal advantages over pets (with rare exception in state law) and service dogs are legally defined at the federal level. Therapy dogs are basically well behaved pets who have proven their manners and social skill to at least a minimum standard so they can visit, but not service dogs in the sense of doing something the disabled owner cannot do for themselves, in effect becoming an extension of the person themselves. Therapy dog owners may have little or no experience with living with a disability. There isn't much more in common than there is with pet owners generally.
If you live with a disability, you may find people here who have a similar background or experience. Thus a person with an ESA rather than a SD should probably feel at home (we do have several members in this category). If you live with a service dog, you'll very likely find someone with a similar background or experience, especially if you're willing to look beyond being disability specific.
Magesteff is really FAST. She's already got a rough draft out that looks like something I would have spent hours or days doing. Hopefully it will be polished and published on the front end of the site very soon.
