Who is responsible for providing temp workers their training, for example on lockout/tagout? How much lockout/tagout training do temp workers need?

It really depends on what the workers are doing and what their exposures are (and how much of it is site-specific) as to the extent of the training, as well as whether a specific OSHA standard applies that has specific requirements for host/contractor work. Generally speaking temporary agencies are responsible for general training and host employers are responsible for site-specific training.

With specific regard to lockout/tagout, there are several layers of training in that standard depending on whether the workers are “authorized,” “affected,” or “other”— see 1910.147(c)(7). Also, that standard has a few specific requirements for host/contractor interaction.
