Anytime your pistol starts having malfunctions on the range, the two most likely causes are lack of maintenance or bad ammo. You can eliminate the first by regularly cleaning AND LUBRICATING your pistol in accordance with the manufacturer's guidance. Once you have a clean and lubricated pistol, you can start ruling out ammo causes.
The third most common failure is user-induced - especially with tiny pistols. A finger resting lightly on the slide can slow the slide enough to make a tiny 22 not cycle properly.
A lot of "bulk" .22 ammunition is VERY dirty, both powder choices and bullet lube that can really muck up a pistol. The smaller the pistol, generally, the smaller the window of operational tolerances - meaning more frequent and more thorough maintenance is the best practice.
To your original question, if you find the report/blast/flash of the LCP in 22 to be objectionable, moving up to the same pistol in .380 is very unlikely to be a better solution. The P365 in 380 is an attractive option on paper, but I've heard lots of reports of reliability issues, especially with less experienced shooters or folks shooting with less than perfect grip technique.
Sorry to not have a "magic bullet" answer for you, but if the LCP in 22 works, and you shoot it well, better that than harsh language. I've been instructing a new shooter (had never been in the same room with a pistol before our first lesson), and she is heck on wheels with a GLOCK 44. ANYTHING in 9mm, including my heavy as heck, super soft shooting Shadow 2 is one round and "nope" for her. She fired one round through my LCP max and it took several sessions to undue the flinch she developed, because she doesn't like the blast/flash of anything center-fired.
So, my advice to her is keep shooting the G44, because she can draw and fire five rounds into a 3x5 card, on demand, in under 4 seconds at 10 yards. She can keep controlled hits on the same target up to 22 yards out - the longest shot she could possibly encounter in her house (she does not want to carry outside the home). At her age, if she never "graduates" to a "real gun," I have minimal concerns for her well-being in her planned defensive usage.
On .22 ammo, I've had really good luck with Aguila SuperExtra 40gr round nose solids. I don't think there's any advantage to a HP in a .22 for defensive purposes - chances of causing insufficient penetration far outstrip any potential expansion, especially out of a 2" barrel.
Best of luck and keep us up to date on your progress!
