"Los Angeles" is broadly not the same as Southern California. If coming out for tourism, one could easily be interested in perhaps 6 or 7 or more counties. Traffic is a problem so planning is important. It's not currently as bad as it was but as things continue to open up I'd expect it to worsen. Not sure what's going to happen with the big amusement parks, they may or may not be able to accommodate out of area quests. That's still under state level controls which can limit numbers, require only "local" reservations, etc. The San Diego area attractions, like the Zoo, Safari Park, Sea World? Check their sites. If considering them, then the west side of "Los Angeles" the coastal area around LAX is going to be a harder, longer drive. The west side isn't all that bad for "Hollywood" - things like grubby Hollywood, Griffith Park attractions, zoo, museums, Observatory - check all of them, the Observatory is really popular and when/if it opens up, you'd need to figure out the visit process, parking, etc., is limited and buses/shuttles may be needed.
I recently visited the California Science Center - in Exposition Park. Needed reservations but they weren't hard to get. It's got a space shuttle. The nearby L.A. County Museum of Natural History has old fashioned animal dioramas that they've sort of updated, but also a spectacular rocks and minerals display, a wing of dinosaur skeletons. There are several museums in the immediate area that you might want to look up and consider. I live in the western edge of San Bernardino county and the drive in wasn't all that bad. There are several important art museums, Getty in west L.A., Norton Simon in Pasadena, Huntington Library, Gallery and Gardens (don't recall the exact name) is in San Marino (near Pasadena). it has important art galleries, the library usually has a range of important books on display, the gardens are fantastic, desert, Japanese, Chinese, traditional, etc.
Should "you" be interested, along with the L.A. county coastal areas, driving south through/along the Orange and San Diego coasts is enjoyable - beach traffic can be rough. Even with May Gray and June Gloom weather (it can be foggy and overcast in the morning, sometimes lasting well into the day). North along the Malibu coast into Ventura County is, maybe, fun, it's "Malibu," and like Beverly Hills and some of the other "rich" areas, that interests some. Drive up the coast to Santa Barbara and beyond is pretty, perhaps less congested. Going past Santa Barbara gets one into the "Central Coast." In may it should still be kind of green. Just the other side of the mountains from Santa Barbara you get into the Santa Ynez Valley, Solvang ( a Danish flavored town) and wine country, lots of wineries to visit, some good eats, too.
I'd expect that if you aren't typically involved with cops at home, you won't be in SoCal., either.
