You will not find them, for a couple of reasons:
- LiIon cells are 3.6 volts each. You can't just drop in 4 LiIons where 4 AAs were, some rewiring would be necessary (series/parallel instead of just series, and then recharging would be complex without removing the cells).
- LiIon battery packs (not cells) have internal regulation and safety circuitry. This is for good reason: LiIon cells, if shorted out or overcharged, will EXPLODE. I don't mean pop a seal and leak some stuff out like an old AA cell. I mean get hot as hell, boil their electrolyte, and blow the side out of whatever they're in, possibly injuring people. This is the reason you never see raw cells, except in electronics catalogs where it's assumed people know what they're doing, and even so when you buy them, they'll come with an orange warning tag in the package.

No. Because normal Lithium batteries use a non-reversible chemical reaction when creating their juice. All batteries are doing chemistry when releasing power. Rechargables use a reaction that's designed to be reversible (the ions can be regenerated electrically). Non-rechargables use reactions that are difficult or impossible to reverse simply by putting electricity across the junction.
