I.e., if you run out of chakra, but still continue to absorb NE, it can disrupt the balance of senjutsu chakra and lead to the usual consequences of body overloading itself with NA (frog transformation/petrification), so if the chakra is low, the absorption should be minimised or complelely stopped since it can become dangerous at this point. So, it still doesn't give you unlimited chakra reserves though.

Fair enough

Kabuto was standing still and not offering any resistance when orochimaru took his chakra whereas jiraiya is in sage mode with 2 other sages on his shoulders. Theres no way orochimaru will have enough time or the opportunity to take his chakra.

Hashirama's regeneration is limited as it can't regrow severed limbs because madara had to use zetsu's arm to heal when the tailed beast removed his arm. Moreover, when dealing with jiraiya in sage mode, you can bet orochimaru will be using his regeneration very often.
