TOFTT.....No guts no glory..

Question, why would you ask her to verify herself AFTER you made plans? Shouldn't this have been asked prior to setting something up? If you're not sure, ask and If she gets pissed then good for you, maybe you dodge a bullet..but asking after?
But I wanna ask, what if you ask...and she tells you that maybe we shouldn't meet....Then a month down the road she starts to get 10/10 reviews. Turns out she'd the real deal. What would you do?? Call her again with your tail between your legs?

I agree with Happy's comment. I think the only additional point to consider is your budget and the session cost. How unhappy will you be if you put money down but really don't like the results?  If it's money you can loose and not feel like it's changing anything for you tomorrow, unless you have some other things that are bothering you I say take the chance.

 
But why the second thoughts now? Is there something you can maybe find that is bothering you -- or is just just a bit of cold feet due to the lack of information (which is just what you had when you made the appointment)? Or is there something you're now thinking about that is changing your gut feeling about the situation? I've found that trusting instincts /intuitions has worked pretty well for me.

If the provider doesn't have reviews or info,  Google search comes up empty when you search the phone #, I would never schedule the appt.  

Imo the absolute worst case scenario here is a lot worse than best case scenario.

I’m a risk taker, but I always trust my gut. If you’re gut is telling you to walk away, then walk away.

Ask her for her website/social media/review info.  
If she is real this should not be an issue.  
You already know what I am going to say next but you guys really need to think with the big head first. Of course she is going to have nice pics and a good bio. She wants you to book with her. "She" might also be a random dude in India who has generated everything that gave you a woody using AI.  
I am assuming you found something that might be off as to why you are having second thoughts. Proceed with caution.

How far out did you schedule? Is it for tomorrow or next week? Can you cancel w/o a $ penalty or a "pissed her off" penalty?
.
I.e., a polite "I need to (cancel; delay; reschedule) our appointment. My company is undergoing some sudden changes and I've got several important meetings that week." or "... my (friend; relative) just went into the hospital and I'm on duty to provide a lot of support (in the hospital; at their house; to their kids; ...)."  "Thanks so much for understanding."
.
... hardly sounds as bad as "I don't know. 'I'm having second thoughts.' I need proof. Show me your badges!" "Badges? I don't got to show you no stinkin' badges! You are now on my official Do Not See list!"

Why not share the link from the site you found her?

When posting threads it’s important to share the relevant information and we can better assist. 🤔  
Smile for me! Personally, I would pass if the provider is not verifiable. The only way I would is if someone I knew personally could vouch for that individual person. Peace of mind is priceless.

If I can't verify a provider to my satisfaction, I'm not going to contact them ever. Let alone, schedule a session with them and then have 2nd thoughts about it.

I have a feeling that if you cancel your scheduled session with her, she'll blacklist you as a timewaster at a minimum.  

Additional thought: if you're going to ask for advice about a provider, at least provide their name and any other info you have about them so that others can provide an appropriate response. Otherwise, it's just wasted space.

No reviews = Either scammer or non-GFE with bad attitide and one shot on goal = PASS!

I am always available for any client but do not ask me to verify myself after you set a "DATE".
