So in my experience, you can usually look up an LLC, that's public information. I looked that one up for you, and it appears to be incorporated at a residential address.
https://opencorporates.com/companies/us_tx/0802460543This is undergrad business knowledge speaking (so don't consider me an authority by any means) but it's not uncommon for people to incorporate an LLC that technically owns their real estate. When I see a name/address like that, I usually assume it's someone incorporating their propoerty for liability reasons.
There's a caveat though. Sometimes they are just holding onto the property as an investment. Like, waiting for a developer to buy it and build a strip mall or another "luxury" condo complex or something. If that's the case, I'll go check it out and see if it's undeveloped (nothing at all built except maybe fencing). If there's no signs explicitly saying otherwise, I'll fish it. It's risky, but as long as you aren't worried about an incidental contact with local cops, who will wncourage you to move along, it's a risk sometimes worth taking. Just play dumb, "oh, I didn't know" and mosey along, and probably don't go back. It's likely they have some kind of monitoring for the property, or it's a problem area for cops and they regularly check up on it. You see 'em once, you'll see 'em again.
90% of the time with commercial properties thaf have ponds, as kong as you aren't sitting on your tailgate next to the water with a cooler full of Natty Lite, the owner isn't gonna care, because the nature of a Limited Liability Company means their liability is limited as far as any mishaps that might occur. Hike your gear in, and clean up when you go so there's not an issue for other guerilla anglers
