The LGPL has:

> This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below.

Which points you over to this in GPL, Sections 7, Additional Terms:

> Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:

> ...

> f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.

This is a condition being imposed by a new law (if/when it passes). Its an attempt at indemnification that is compatible with the law. It seems to pass the reasonableness check.
