Casual coffee chats or phone pen pals for single immigrant 67-year-old mom?

I have a pretty niche inquiry. My mom is 67, originally from Hong Kong, has been in the states for 30+ years, divorced for more than a decade. She goes to senior centers in the city to fill her days, but is wary of getting too close to others who may be clingy or become dependent on her; she's had some negative experiences in the past. She has a lot of time on her hands and she expressed thinking it'd be nice to have someone to spend some time with, a companion of sorts, who is also independent enough to have their own life and will respect her own need for some alone time.

I searched up some senior online dating sites but the bots are really aggressive and plentiful on OurTime/match.com, she was more drawn to Asian profiles and I think many online dating scams target older Asian women. She actually has kept matching and talking with bots despite acknowledging my warnings because I think she finds talking to bots to be validating and more entertaining than having no one to talk to. 😭

I'd love to find and help her vet some real people her age she can be pen pals with or who would actually meet for coffee in the city, especially folks of a similar background she may be able to relate to (she's probably more motivated by romantic interests but a female friend or two might not be so bad). She owns her own condo and has three semi-accomplished kids, has some college education but is also very frugal, has limited income and can feel out of place and snubbed in higher-class or majority white settings. I looked at r/SFr4r first but the majority of the posts are of a different nature, I felt like the audience would be wrong there. Maybe you know someone who might fit the bill, or have some other suggestions? Feel free to DM me.
