Your employer should be providing the tools for you to do the job, including locally run software.
So yes, they should be providing an office suite whether that be Office365/ Libre Office / etc.

It's much the same as using my own home to work in. If they were required to provide me with an office, and I had to use it, whatever benefit there is would not go to me.
Why? Skilled tradesmen frequently own their own tools, and many wouldn't have it any other way. You can bet your ass many of them have spent an order of magnitude more on their tools than a few measly software licenses ($20 for a text editor? Extortionist! But a cheap cordless drill costs several times that...) In California, employers are only required to provide the tools necessary for a job if they're paying you less than twice minimum wage, a bar you surely clear.
Software developers who work as independent contractors generally own their own equipment and software (in Australia that's actually one of the legal criteria for determining whether someone is a contractor or an employee for taxation purposes).
Whereas employees generally use company-supplied hardware and software, which is to the employer's benefit as they have full control over it.
But that's really by the by; whoever is procuring software to be used for commercial purposes, it is reasonable to expect they would purchase commercial licenses to help fund the development of their tools.
